Mouse click?

I went over the API's, but is there any way to get a mouse click event, or check if either side of the mosue is depressed?

With the next release, which is right around the corner, the MouseAPI will be upgraded with a two new natives:

//===================================================
// Mouse API constants
//===================================================
globals
constant integer EVENT_LMOUSEUP = 0
constant integer EVENT_LMOUSEDOWN = 1
constant integer EVENT_RMOUSEUP = 2
constant integer EVENT_RMOUSEDOWN = 3
constant integer EVENT_MMOUSEUP = 4
constant integer EVENT_MMOUSEDOWN = 5
constant integer EVENT_MOUSEWHEEL = 6
endglobals
native TriggerRegisterMouseEvent takes trigger whichTrigger, integer eventtype returns nothing
native GetTriggerWheelDelta takes nothing returns integer

If you use the EVENT_MOUSEWHEEL, you can use the GetTriggerWheelDelta afterwards, to see what way the wheel scrolled, it's positive if up, and negative if down.
