Anyone got some ideas why this splice is not working in this hitTest routine?



for(var b=0; b<blastArray.length;b++){
                for(var s=0; s<boxArray.length;s++){
                    if(blastArray**.hitTestObject(boxArray[s])){
                        //trace('HIT!!!!');
                        score += 5;
                        value1 += 1;
                        trace(blastArray);
                        trace(boxArray);
                        boxArray[s].die();
                        blastArray**.hit();
                        
                        if(boxArray[s].alpha <= .02){
                            boxArray[s].parent.removeChild(boxArray[s]);
                            boxArray.splice(s,1);
                            
                        }
                        if(blastArray**.alpha <= .02){
                            blastArray.splice(b,1);
                            blastArray**.parent.removeChild(blastArray**);
                            
                            trace('remove entry');
                        }
                        
                    }
                    
                }
