Alt supresion and spawning of runes

Ok so I need two things:
1. A way to supress Alt button, so it won't work for a player trying to see the units
2. What is the easiest way to make a non-leak multi rune respawn system. When a unit picks up the rune in 15-35 seconds (random number in that interval) a rune will pop up again. There are like 4 types of rune and for each type a 4 different runes. I want a field to spawn only the same types of rune. This is out of my skills. Any help?

1. is impossible, you can use Aloc or something in the units so they don't show the health bar / are unselectable.
2. local variables and waits

For number 1, adding and removing the 'Aloc' ability from a unit makes its hp bar not show up and it isn't click selectable (only 'drag selectable').

You could also disable drag selection and set the selection circle size or whatever it is called to something negative, I think that makes the hp bar not show.

Right, selection size -1 will result in both the selection circle and HP bar being hidden.

1. Set up a trigger that if a player presses the Alt button then either they move somewhere else or defeat the game for the triggering player.

2. Unable to help you there

That's bullshit, you can't detect when a player presses the alt button.

Yeah it helps Griffen, but it makes interface a bit quirky. I'll see if it affects the gameplay the way it shouldn't.

I stand corrected I thought that with the Keyboard event you could do that.

I didn't realize that it was for the arrow keys only
