how to fix this syntax error?

Please show me "DEF GUN"

@BIG_TEXTER GUN is a variable, not a function What are those lines supposed to do, we need more information.

You are just listing a bunch of expressions. Maybe you meant to write an assignment or use them as parameters for a command? What I'm saying is, writing... 10,20,15 ...doesn't really mean anything. Meanwhile, writing... A=10:B=20:C=15 ...or... SPOFS 10,20,15 ...does make sense.

@Oscar I'm still confused, I put GUN as = to 165 so it says... GUN=165, you just cant see it because its near the top.

You need to write GUN=SOMETHING every time you want to assign something to GUN, not just once. For example... GUN=10 GUN+20 GUN-5 ...the second and third lines won't change the value of GUN. They just serve as expressions. However... GUN=10 GUN=GUN+20 GUN=GUN-5 ...will change the value of GUN accordingly.

@12me21 i dont know what the lines do yet because i cant fix the syntax error to test the game, all i know is that im making an asteroids like game *you know the Asteroids arcade/atari game*

What do you mean you don't know what the lines do? Aren't you the one programming this?

well, im guessing the way to fix it is by adding in the commands before it, i just dont know how to add in LINE and CIRCLE commands...

You need to use SmileBASIC's graphics commands. They all start with a G. You can use GLINE to draw lines, GCIRCLE for circles and GCLS to clear the graphics screen. I suggest looking at their manual entries, but I will give you a basic rundown.

Parameters in brackets aren't necessary. GLINE X1,Y1,X2,Y2,[COLOR] ...This one is pretty self-explanatory. You draw a line from point (X1,Y1) to (X2,Y2). GCIRCLE CX,CY,R,[COLOR] ...For this one you specify the center coordinates of the center (CX,CY) and the radius R of the circle. GCLS [COLOR] ...This one "clears" the graphics screen by filling the entire screen with a single color.
