Missing Type Specifier

I get the error "Missing Type Specifier in function CleanUP() which means i don't have TImage. However Function LoadSprites() is where the image handles are being specified. All Function CleanUp() does is remove all the game references from memory to conserve it. Do i have to declare my image handlers again to destroy them?

Code Broken

I cannot run your code but I think you need to declare the global object outside the function, or it is just a static object

Look at:

a=8

Test()

Print a


Function Test()
Global a=3

End Function

and

Global a


a=8

Test()

Print a


Function Test()
	a=3
	
End Function

or even

Global a

a=8

Test()

Print a


Function Test()
Global a=3

End Function

(I got too much freetime)

I thought Global meant it could be run anywhere?

Global:
http://www.blitzbasic.com/bpdocs/command.php?name=Local&ref=2d_a-z
http://www.blitzwiki.org/index.php/Global

If a GLOBAL variable is defined IN a function, this means that variabile keeps its value intact for the next call, but OUTSIDE of this function it can not be 'viewed'.
In your case you want to access to the variabile in every place of your program, so you need to define global externally to any function.
Sorry for my bad english...it's early morning...

I fixed up code a bit including a few strings i forgot to include in the Load Image Code. I had
and Function CleanUp missing (). Now i get this error:

Compile Error: Identifier 'Ball_Image' not found

Code Being Fixed

Your Code:

Function LoadSprites()
'Load Graphics
Global Ball_Image:TImage = LoadImage("Incbin::Sprites/ball.bmp")		' Ball
Global Player1_Image:TImage = LoadImage("Incbin::Sprites/bat.bmp")		' Bat
Global Player2_Image:TImage = LoadImage("Incbin::Sprites/bat.bmp")		' Bat
End Function

Try:

Global Ball_Image:TImage
Global Player1_Image:TImage
Global Player2_Image:TImage

Function LoadSprites()
'Load Graphics
Ball_Image:TImage = LoadImage("Incbin::Sprites/ball.bmp")		' Ball
Player1_Image:TImage = LoadImage("Incbin::Sprites/bat.bmp")		' Bat
Player2_Image:TImage = LoadImage("Incbin::Sprites/bat.bmp")		' Bat
End Function

You have the same problem in other functions too.

Why is it i have to do this? Also if i make that Global to the entire program and run Function CleanUp() will i be able to call Function LoadSprites() and recreate the variables or will i get a runtime error?

I would say yes, you can, but I cannot see your code

Because a global within a function is not known outside the function so loading anything in a function that is never used again makes no sense ...

I want to use as little memory as possible so i want to load all my images and stuff only when the game is started. Then after the game ends everything is removed from memory. If the user wants to play again all, the sprites, sounds and variables are loaded again. This is so the game uses as little memory as possible. Also because every part of my game will be controlled from a function, if i want to add additional modes latter, i can just create another function for that game mode and simply use the excisting functions for the main portion and simply create another function for the mod.

Does everyone understand me a little better now?

Ok, for some reason this is giving my a Missing Type Specificer Error, even though i added it to the top of my program which should make it global.

fixing

You need to take out the Global declarations in your LoadSounds and LoadSprites functions as they are confusingly creating new variables that are in fact static and hence the global variables declared at the top of your code are remaining unchanged, or as in your case causing compiler errors.

Ok, i added the player movement code. However when i try it out nothing happens. I have flip at the end of my loop. Also SetBuffer BackBuffer no longer works. I have the Gadget Repaint Event in my loop. Any ideas?

fixing

KeyDown, KeyUp, etc. will not work if graphics is not set, but you can get input from the event queue (But I have not used the GUI very much)

SetBuffer BackBuffer is also using graphics.


You also need a timer, e.g.

Local timer:TTimer = CreateTimer (60)

<AND>

Case EVENT_TIMERTICK
RedrawGadget GraphicsWindow


Have you made pong without a GUI because what you are doing is WAY harder then it needs to be.

Indentified TTimer not found.

You are missing the needed module for timers

I wouldn't use frameworks until you release the program to prevent this kind of problem.

Nope nothing happened when i added that.

not longer in use

I wanted to create my game using GUIs since it looks nicer then just a black screen and the game immediately starting. I wanted to add the ability to give instructions and stuff. The main problem stems in the fact that graphics no longer has a windowed mode. Wizard Wars in BlitzPlus did this easily, so why am i having problems trying to do it BlitzMAX?

P.S. No i have never made Pong. This is my first time.

You should try and split your code in to a GUI part and a game part, why not make pong without a GUI first?

Anyway, like I said Keydown is not working in you code, the GUI is blocking it (or because you have not used Graphics), I think you need to get it as an event, and then maybe store it in a global

Also BlitzMax will load all the libraries if you take out framework and the import commands, and you can put framework back it when you know what you will need.

Alright i'll do the entire thing from start. I'm having problems too though. The command Text doesn't seem to excist.

Text 0,0, "Hi"

Compile Error: Identifier 'Text' not found

DrawText (see the Max2D documentation for further commands)

This code doesn't work and causes the application to freeze. Additionally the DrawText command doesn't work. My loop is not endless so why is it freezing up?

Now i'll never be able to sell it because its not my code!

You know what i'm thinking of just leaving this community for awhile to relax. I don't like BlitzMAX too much. Its more difficult when compared to BlitzPlus. No offence but, i just need time to relax. Thats not to say that i woun't return.

Did you uncomment the the Incbins and load functions?

No, but i'm gonna give this a rest and work on it in another language for now. I m ight return soon.

Dark Mars Software:
Your free to use the code for what ever you like,
BlitzMax is not that difficult, I was just showing you some new stuff you CAN do in blitzmax, you can just use the old stuff too if you like.
