when trying to set a movieclip as an addchild, my hero still goes under it instead of walking on it.
i hav tried…
```auto
addChild(level.mc.building); //where level.mc is the level and building is its background
```
and ive tried
```auto
hero.mc addChild(level.mc.building); //where hero.mc is the character
```
in both versions the hero walks under the movieclip
any suggestions?

```auto
setChildIndex(hero,numChildren);
```
change the index of your child objects… 0 is the back and last number is front. so if you always want your hero to be on top keep his index last. but if you want to have him go behind stuff, say like a tree, set the hero’s index after the tree, so the tree is say a 4 so put the hero a 3 or less.
edit: lol oops had my numbers mixed up

Can you show a graph of Ur clips structure?
Anyway, maybe the simplest solution will be the best
```auto
addChild(hero);
```
