PlayBASIC LIVE : Saving a New Project ( IDE BASICS )  2018-04-14

This video takes the new playbasic programmer through a couple of examples that demo how to save a project and create folder using the PlayBASIC IDE (Source code editor)  -

1) In example one we write th classic Hello World example and then show how to save it as a project to the desktop

2) In the second example we take this further by adding some sprite media to the project manually then demo how you might load the sprites and display them.







hello welcome to another

our video today will be doing sort of

one of the fundamental things about

setting up PV to make a game I will be

opening the IDE saving our projects and

copying some media to that project and

then loading it so a little bit to get

through bear with me but we will will

endeavor to get through it together

so first of all let's open up now play

basic I'm using a what revision this is

but it's not got a few different

revisions but you all look pretty much

the same as this

well me yeah when we open the IDE the

blo basic idea be the code editing

environment if all defaults and we'll

open up a project for us that's empty so

we could just type some code in here you

know probably well and sorry about the

terrible example wait Kate you'd have

fun to run it and we have code up or

running press ok should end back to the

IDE

now that's fine if you just want to mess

around quickly and try something out but

sooner or later you're going to want to

create your own projects rather the load

other people's existing work okay so if

we want to decide this as a project that

we can reload some other other time we

need to go up to file I'm down to save

as and it's opened into full screen for

some reason now what I'll do today is

all at the moment its open I've been to

another project I was working on before

but this time we'll go to desktop and

here is the project name

it's down the down the bottom here and

it defaults to project 1

but we'll call this hell hello world the

project I will project

yeah if I save that the files there'll

be two files and watch it a couple of

our other files saved to your desktop

all spread over your desktop yeah

what you should do is create a folder

okay

create a folder called hello will

project

whoops shall add time by now hit enter

yeah walk into that folder now we'll

save our project into this location so

it made a folder now PB will save our

project file the source code and some

stuff to do with the icons and things

like that they can be associated with

your project into that folder so there's

gonna be a little bit confusing

initially the author name here hasn't

been set because obviously in the

settings here it doesn't mean yeah so

this all be yeah oh you know

I'm just would care okay so that project

is there saved if I minimize this and we

look on the desktop there should be a

folder there is it's a folder called

hello world project which we created we

enter that folder we've got three

different files we've got hello world

project EBP and we've got a hello world

product PPR and main now the main file

is actually the source code the PPP

project which is an acronym for play

basic project file that is actually the

project file can also your it's the well

it's the project file yes which it

contains a bunch of settings about your

project mostly and this is the code go

to the IDE let's say let's close the IDE

close this this project so we can just

reload it by going back to reload and

I'm here which is often what I tend to

do actually all depends on whether

you've got associations set up I have it

on this computer obviously so you can

just drag and drop the file to the IDE

as well no silly windows there you go

and and once that PBP project file

that's the one there's all the

information about this project so your

product you your product might have

multiple source files associated with it

yeah that's we go up here to the project

menu

going to manage project we can add we

can add an existing file source code

file or we could make a new file yeah

we'll just call this one my include my

include file and here showing us the

order in which that the files will be

compiled or pieced together when they're

compiled I want my include file first

and I want my main second so that's all

fine hit OK at the top here it out right

we've got our main so this code here and

there include so I might make over here

you might have a collection of functions

that you use a lot or just something

that it's commonplace it but you don't

really want them mixed up in your main

program so we could we could make it

function you know print read

message so this will just print whatever

we sent it but we might change the ink

color so what Ward well I wouldn't

normally deal with it this kind of its

kind of retained so I always get the old

ink color old ink ask for the ink color

then I would set the ink color that I

wanted here our GPA will make it a

bright red to our print and then we'll

reset the ink to what it was initially

so it looks okay in this like should

compile but just test that yeah

everything compiled and that band fine

might go up and give it a quick save now

yeah follow the back here on the desktop

I'm sorry we're bouncing around

everywhere we now have our include file

and it has a backup as well

every time we include sorry every time

we save we have at least two backups

so our project now contains six files

bro simple hello will program just

closed that fall and go back to play by

Singh I just grabbed that go back to

mine so it print hello well and we put a

print here oh sorry

print read we're calling this function

make it a big long line of characters

let's say if I have to run there we have

it hmm so we've include files like

managed through the IDE like this

they compile from left to right so the

ones on the left over here might be hard

to see I'm sorry her when we hit build

our let's paste into the MA the the file

source code and then the next file is

appended to that it's all bundled

together and send like a viola look upon

just compiles one big chunk of source

source code rather than African double

stitch for files that might require

pre-processing by something else like

the idea in this case okay that's our

very first project so let's do it again

this one will have some meteor and it

will make it loading you mean just

something like that so close that

project and it's not on scratch so

restart play basic we didn't have to do

that just till first seho example it's

time I know I've had some sprites before

these sprite and files here there's a

free night it's very cool isn't it

just occurred to me I didn't didn't keep

the URL my quite sure who made these now

but they've got cool away evasion couple

of different types and imagines some I

might wait some code that loads

animation displays on-screen who knows

but for now we need to set up a project

so go back to play basic might step hi

my author name J probably else looks

pretty good

most I products tend to have a bit of a

a blurb at the top so when I open them

up I actually know what the hell I'm

looking at when you write so many things

over such a long time actually it can be

a bit confusing you know say my game my

game demo be one I care okay it's our

source code it's kind of nothing at this

point we haven't saved anything let's go

up to file and to save as and at the

moment it's it's sitting inside our

previous projects we don't want to save

it there and we want to go up a level

and I like I'll save it to desktop again

so I'll make a folder on the desktop

we'll call this I don't know what we

call it what do you think we should call

it will call it down game project

example that'll do I made the folder but

now we have to go inside the folder and

save file name here to something more

descriptive so nice night game you know

he era all the animals outside

was it not game sprite example she

always I could type in this keyboard

there we go

looks okay that'll do us hit enter and

that will save the project to the

desktop so we hear over the desktop here

and we can see our folders made and

inside we do have a pv source code and

our project file for this project

now what I would normally do is I would

actually make a folder in here but no we

call it G of X which is just short for

graphics by the way hmm

and then we might go into it for how go

sprites yeah let's just copy that across

it's got more files in there than what

we actually need we'll all be there's

the PNG files okay so we're gonna

project files our source code our media

files are in that one place as well and

they look at different names and so

forth it's all f2 load those names

manually okay I just go back to play

basic now that media is kind of set up

and ready to go I can save any time just

with ctrl ctrl that's just like you know

notepad and those kind of projects so to

get the image into memory all we do is

we use the command load image F or tell

it where this file is and the farm will

be relative to where the source code is

saved and this is why I would say the

save their files inside the project so

all the material was actually it's

actually it's actually in one flies what

the hell was that cold okay

it's free not big

sorry I should have known that so it's

inside the graphics file though it's

inside a folder called free nights and

then inside that is a father called PNG

and inside that is hopefully L sprites

you have open the wrong one ever yes I

have terrific mm-hmm I wish the mouse

had moved it there we go free night pay

and J I just love that far away attack

one describe the name yo don't pay NJ ah

okay so we've got the farm I'm now we

need a slot to light this thing into

it's all cool I'll bet I'd be lazy and

use image 1 now if I just do a quick

courtesy save hithere52 run we didn't

get any errors and if the file name is

wrong and I'll just prove this to you

right now put some chick garbage in

there we'll get a runtime error like

that it's telling us it tried to load

some graphics and could not find it it's

the wrong line number which is very

inappropriate but

so the code did compile and run and

execute correctly but we didn't do

anything with the image so how do you

know well if it's loaded quickly or not

so mode the previous image enters into

image slot one so we use it here well

draw it x and y 200 200 can we want draw

it transparent and destroy it all flat

so all of the maths color will be

displayed I'm pretty sure these images

here have alpha channel so wife to

probably fiddle around with this in a

second but let us get on screen now

withdrawn the image the screen call sink

call white key still be there save and

oh there we go it's on screen but the

character the sprite is massive I didn't

realize it was so much we can change the

products default window size let's go up

to project settings and the screen over

here 800 yeah let's go bit bigger than

that about 960 by 700 you know it's a

better size this should be set to 32 yet

even or in windowed mode you know K

again I like to do I like to save a lot

actually up that sort of person right

yes screen is ytp but we are actually on

screen so we have loaded an image we've

drawn this thing to screen and we've

synched we're sitting there waiting for

something else to do

so that's why all that all the rest to

do for like Singapore own project but

let's kick this on a little bit further

we'll just check what kind of

transparency this image actually has

that that will have an impact on how we

load the image that's why I want to

check so clear the screen upfront to a

bright blue we run it okay we can see

the sprite the area here all this area

here that's how at the transparent area

if you're going to use this in a

production in your actual ending your

actual game you want to make sure that

all this Daddy areas cut out it's just

gonna cost you performance like crazy

but for now we won't worry about it

I'll say this to true so we'll draw a

transparent well yeah okay so we neither

like this image as an a FX image we'll

see if it even loads now there's a

version of load image called load a FX

image the rest the code doesn't change

yeah we have it where on screen so we're

up and right okay so good at

transparency working the animation

itself I don't know what having friends

with anime show anything let's see how

much homework on what's in this ice

we're letting out a tax sequence looks

like there's ten files over there a

kolbe attack so what we would do well

what we could do is add a loop for loop

equals 1 to 10 we can load these into

image slights will be a little bit more

considered so let's say that slot 100 we

were alone air frames into slot 100 to

110

so I might need to do there is actually

chop that off I'll be I'll start loading

at 101 want it just like you're saying

yeah so I had like this mice that looks

ugly but we'll get our designer impact

so now we have to dynamically create the

file names or Jews or we're two quotes

in there remove that one don't we make

two strings put a plus two pluses and

here we use the string oops and loop

that's a Lotus our sequence into memory

and then we'll below into image slight

one hundred two hundred and ten between

hundred and hundred and tangent good so

if we try and draw this image one though

that will fail and I'll just prove that

to you

boom didn't work that first image now is

actually one hundred and ten sorry

one hundred I should say let's try that

we've got something in back to normal

cool so we've loaded our images it's

probably taking a little bit time they

probably bigger files and what you might

expect let's make a loop to display the

frames we could do something similar we

could just go for loop equals 100 this

time this is the actual frame maybe the

image in memory we're gonna be using to

110 so the program will run ten times I

think we might have to we will have to

actually add some extra logic to this

but so it's all there for the time being

well draw the frames will draw the

current frame at this position so the

animation should play out

might move up the screen a bit though

was a bit low before so we're drawing

our frame calling stink but we also need

to clear off the previous frame soldiers

inside the Louvre after a run there you

probably won't see much interesting

it'll just kind of run through the

animation too quickly and it did like a

110 so we waited nine frames and the

last frame is going to be sorry ten

frames from 100 to 110 that means that

frame 100 is the first frame at frame

109 as the last room that's 10 frames

yeah just run against they've got no

errors cool but of course we need to

slow that down so I'll just be a bit

cheesy here and I'll add I'll just tell

people to set the frame rate to

something

what about 10 frames per second so we

should see all the frames being rendered

yeah that's better there you go that's a

very very entry-level way of saying up

their own project right the room meeting

you're into it just say that again so if

I close the project down close Peavy

down close all these windows up here

this is our project that we just made

I'll put this on the on the forum with

the video so you can come and tell look

at it yourself

the folder just contains our night game

sprite example it also has the code with

it if you look about in no pages there's

just text there's nothing special about

it

and if graphics follow has our free

night

animations which has got a lot of a lot

more frames there fee to tinker around

with maybe do something with him who

knows anyway that's how I normally iced

all my projects and set them up it is a

little bit daunting the first time you

do it and yeah I don't beep don't be

frightened of it it you probably will

make a few mistakes the first time you

do it so actually give it a go get used

to how the quirks of the play basic idea

and before you start your big UB

projects or anything just to make sure

you understand how it likes to do its

work and that you don't don't lose

anything in the process because it is it

is possible for you to save over an

existing project if you're not careful

so just remember that anyway thanks for

watching and I hope that was abuse

--fill have used to somebody and we'll

get to some other time bye

hey kev

i always learn something new from your videos. with this one i learnt that you can drag a project file into the ide. handy.

the free graphics website is good. it has lots of freebies.
maybe use some of these to show a menu with buttons demo, and use some for a basic platformer for a later demo?
i think these graphics are vector based, so they are scalable in a paint program, without losing quality.

  stevmjon
It's easy to start a program, but harder to finish it...

I think that means i am getting old and get side tracked too easy.
