Thanks, That really helps me very little, because I still dont know what to do, but I might know what the problem is.

(I would post my code, but its a mess that I dont want anyone to be going through anyway.)

(Edit: Went back over my code, found out I STILL dont know how to fix it, so I will post the problem code here... along with all code that it influences)

This is supposed to be a piece of a 2d Fighting game.

The Problem Code -

+ Code Snippet

If Sprite Hit(4,5) and P1Highpunch=1 and Player2X<620 then Player2Life=Player2Life-5:Player2X=Player2X+20
If Sprite Hit(4,5) and P1Highpunch=1 then P2Life=P2Life-5

The Player 2 Version, which the Problem version happens to be a direct copy of (this one works for some reason)-

+ Code Snippet

If Sprite Hit(6,3) and P2Highpunch=1 and Player1X>0 then P1Life=P1Life-5:Player1X=Player1X-20
If Sprite Hit(6,3) and P2Highpunch=1 then P1Life=P1Life-5

Player 1 And his Arm

+ Code Snippet

Sprite 4,Player1X+P1ArmX,Player1Y-P1ArmY,Player1Arm+11200
Sprite 3,Player1X,Player1Y,1

Player 2 and his Arm

+ Code Snippet

Sprite 6,Player2X-P2ArmX,Player2Y-P2ArmY,Player2Arm+21200
Sprite 5,Player2X,Player2Y,2

(Oh, and the Player2arm+21200... thats a little code I set up, since the fighters are supposed to be customizable, and each one has a different graphic per limb)

I use darkbasic classic and i practically have no experience.

Obviously you're using a sprite somewhere. Without posting your code it's up to you to figure out where.

Uhh... sorry bout that, I was posting a rather lengthy edit and never read your reply. The edit includes all the code involved... I think...

(EDIT) Found the problem, turns out it wasn't registering sprites 5 and 6 because I hadnt made them yet, I made them after the problem code. Its fixed now, and I seriously doubt I could have figured it out without the help.

The most common cause of "bob/sprite does not exist" is when you do something like:

if sprite hit(4,5)

and, for example, sprite 5 doesn't exist / has not been created yet.

Are you sure that all of the sprites you are using in your sprite collision code have been previously defined? (via the sprite function).

Cheers,

Rich
