arrays - Positioning a movieclip onto another movieclip -
i'm creating game if hit zombie zombie dies , head sent in direction hit. have 2 movieclips zombie , zombie head. once zombie hit play dying animation , remove , @ same time zombie head added dying zombie , blown back. have done code hittest , zombie dying , respawning can't seem position , add head dying zombie when hit. how can this. thought this, added in playdeathanimation function in zombie class did not work:
for (var i=0; < movieclip(parent).zombies.length; ++i) { var zh = new zombiehead(); zh.x = movieclip(parent).zombies[i].x; zh.y = movieclip(parent).zombies[i].y; zh.rotation = movieclip(parent).zombies[i].rotation; addchild(zh); } i have 4 classes
