What is the difference between onMouseUp / Down and onPress / Release events in Flash?

Question

In Flash, there seem to be two sets of mouse click events:

• onMouseUp, onMouseDown
• onPress, onRelease

Is there any actual difference between these events? I cannot tell from the documentation, and I did not notice anything in actual use, but it seems strange to have two different sets of names for the same main events. Am I missing something? Is there any difference between the two?

Clarification: this is ActionScript 2 code targeting Flash 8.

Answer 1

onMouseDown and onMouseUp are common events that can be heard through Mouse.addListener (). They fire regardless of where the mouse is clicked.

It seems that mouseUp / mouseDown events will fire even if the mouse is outside the clip, and onPress / Release automatically checks to see if the mouse is in the clip before processing it. I could have sworn I experienced this, but I just tested it, so it shouldn't be.

onPress and onRelease retain control over the AS2 code, they were supplanted by onMouseDown and onMouseUp in AS3, which you can read about in the AS2 Migration Guide .
