Trigger questions plz help!

have a few trigger questions

1. How can i make it that if a player presses the up arrow the unit will move in the direction he is faceing untill the player lets go of it

2. how can i make it so a unit will attack ground if the player click on a region(and that ground being that region)

3. can an ability like Cold Arrows be used when attacking ground?

4. ....everything good ends in four dosent it?

1 more qusetion,
how can i make it that if a unit has no mana,and aqires a target, it will not be able to attack

Edit: Nvm i got it, but heres a problem, whenever a player presses Up arrow, or trys 2 attack, the game closes all the sudden...wats up with that!

Use a condition on the attack trigger to verify the unitstate mana is greater than whatever you want.

As for your crashing, I'm not really sure what's causing it. I just typed up a quick version of a "holding up = moving up", and while it only worked once (guess triggers can only be turned on/off once), it didn't crash anything.

I don't have time to look at it for now, but if you post it maybe someone else can help you...in the mean time, sorry if it was something I said! :////
