hit assignment problem

[nerkn]

I defined 4 platform which our hero will run on, this snipped wont work

for(var i=0;i<4;i++){
    sprite.hit(wall2[i], spriteColl)
}

but this works

for(var i=0;i<4;i++){
    wall2[i].hit(sprite, spriteColl)
}

spriteColl is collusion function.

spriteColl = function(){
        sprite.d*=-1  ;
    };

error is p2 undefined in mibbu.js line 260

258 for(element in MB_collides[loopIndex].hits){ 259 p2 = MB_fixedIndexColl[element]; 260 p2Top = p2.posY + p2.cZ.t;
