layerDepthForChild ( float zIndexMaxComp, O2DMainItem child, float zIndexMaxChild = 100 ) : float |
gets the layerDepth for a child composite. It calculates it by first getting the composite (parent) layerDepth the standard way (via zIndexMaxComp) and then subtracting the inverse of the child (O2DMainItem) layerDepth which uses zIndexMaxChild. For this to work intelligently zIndexMaxComp should be the standard scene.zIndexMax value and zIndexMaxChild should be a much higher number. The reason for this is so that the parent component has a small offset to use for each child and so they dont overflow to the next zIndex. Example: parent is 14. Any children must end up being between 14 and 15 so they dont overflow on top of another composite. |
