Title: PLease help me on my first project
Post by: badrush on 2009-Feb-08
So.. i started looking at the tutorial and then at the samples and made this for an experiment:
I have programmed pretty much in gamemaker before..

Code (glbasic) Select

GOSUB Init

main:
GOSUB MoveAll
GOSUB ShowAll
GOTO main


SUB Init:
DIMDATA player_x[], 450
DIMDATA player_y[], 450
DIMDATA lifts[], 0
DIMDATA gforce[], 0

LOADSPRITE "ball.bmp" ,0
ENDSUB


SUB MoveAll:
FOR num=0 TO 1
IF KEY(57) AND lifts=0 THEN lifts=20
IF lifts>0 THEN player_y=player_y-1.7*SQR(lifts)
IF player_y<450 THEN player_y=player_y+1
NEXT
ENDSUB

SUB ShowAll:
FOR num=0 TO 1
DRAWSPRITE 0, player_x, player_y
SHOWSCREEN
NEXT
ENDSUB


When executing the code i got this:
compiling:

and so i did.
thanks in advance.

Hello!

DIMDATA is for putting values into an array, use GLOBAL instead, at the start of the program:

Code (glbasic) Select
GLOBAL player_x = 450
GLOBAL player_y = 450
GLOBAL lifts = 0
GLOBAL gforce = 0


This will declare the variables as local and initialize them to the values.

To make an array you put squarebrackets behind, like this:
Code (glbasic) Select
GLOBAL object[5]
This gives you an array with five slots in it, numbered 0 to 4. You access them by typing:
Code (glbasic) Select
object[0] = 450
object[1] = 40
...
Or you can initialize all the slots in one line like you started in your program:
Code (glbasic) Select
DIMDATA object[], 450, 40, 0, 0, 0

Thanks for such quick answer.
Im glad i understand exactly what you said since this is a new program for me. =D
