IPhone: ANIMCOLL

[BigAnd]

I think there is a bug with ANIMCOLL on the iPhone.

It causes the debugger to stop with an EXC_BAD_ACCESS or the app to just terminate if in release mode.
This is of cause when there is a collision as the app works fine until then.

Oh, I had a bug in that loop. I'll upload an update now.

[BigAnd]

Excellent. Thanks for the quick fix 

[tatakamucher]

The same bug appears in 118, sometimes if two anim collides the game crash, in the update 202 was the same

[Kitty Hello]

debug the position of the crash. Then make a 3-line program (loadsprite, sprcoll) with hardcoded numbers. Does it crash?
Otherwise make a small example that crashes. I'm so sorry.

[tatakamucher]

This is my code, when i use in 10.118 the bug crashes the game about 1 of 20 collisions, when i use 202 is about 5 of 10.

Code (glbasic) Select Expand


IF ANIMCOLL(343,locov, mx,locoy1, 6,0, cositas[i].x, cositas[i].y)
addexplo(cositas[i].x, cositas[i].y,0)
PLAYSOUND(123,0,1)
cositas[i].z = 0
balloons = balloons + 1
ENDIF


i change the line "if animcoll" for this

Code (glbasic) Select Expand


IF cositas[i].x+20 > mx+5 AND cositas[i].x < mx+55 AND  cositas[i].y < locoy1+86 AND cositas[i].y+40 > locoy1


and the game works fine. 

[Kitty Hello]

please make a 10-line example that reproduces the crash and zip the project for me.

[tatakamucher]

this is an example, in the original i use arrays with types to the enemies and sometimes in the collide crash the game and sometimes not.

        anim2()

FOR i=0 TO GETMOUSECOUNT()-1
      SETACTIVEMOUSE i
      MOUSESTATE x#, y#, b1#, b2#
next

function anim1:
inc animation,1
if animation > 8 then animation = 0

drawanimation 1,animation,x,y
endfunction

function anim2:
inc animation,2
if animation2 > 8 then animation2 = 0
drawanimation 10,animation2,x1,y1
IF ANIMCOLL(1,animation,y,y, 10,animation2, x1, y1)
PLAYSOUND(123,0,1)
endif

thanks

post the example1+2.png, too, please.
