Alright basically I want to make it so when i duplicate a movie clip, it sends its instance name to a function thats on the main timeline and executes the actions from there, for example…
I duplicate a movie clip of a block, and in its onClipEvent(load), it contains, _root.fallingBlock(instance name).
Then on the main timeline there is a method, called fallingBlock obviously, that takes the instance name as a parameter and runs through the given code, such as…
function fallingBlock(instanceName) {
_root.instanceName._y += 5;
}
Thnx in advance
