qestion...

well this is kinda hard to explain..but ill try..

when a u click a ability and your crusor turns into that targeting thing, is there a way to make it so the player always has that targeting thing and when he clicks it dose the ability where he targeted?

i know this well stop the player from doing other things, but i dont care.

If you gonna trigger the spell you can use the Channel ability and select what the player targets and stuff.

You could disable selection, select the unit for the player, and then use the forcing of the interface to make him have the targetting come up whenever he is ordered to cast.

how would I exactly do that?

Well then he would have some trouble moving around

well i dont want the guy to be able to move around, ill find a way to work with it, now how would i do that?
channel ability, disable selection, i dont know how to do that...

At initialisation:

Game - Disable selection
Selection - Select unit for player

Then I think there is a trigger for forcing an interface button; use it to force the right one (use the search for trigger).

Then, when it is ordered to cast, reforce the interface button. You may have some trouble with them cancelling it; can't think of a way around it ATM, apart from stopping the unit whenever it is ordered to do anything else, and forcing the button again.

well i searched interface button.. dident get anything i think u were talking about... i made a trigger to force the player to press the hotkey for the ability but i dont think that was such a good idea... what is channeling ability and interface button?
to force the player to press the hotkey i did
events: every 1 sec of the game
actions:force player 1 to press S (which is the hot key)
