How to kill a unit that touches something?

hey, i want it so that when say... Ling touches a reaver the ling will die. I don't know how to do this, and ideas? thanks

 

Ok ,
This is how you keep the location on the unit

Code:

 Requirements:
always

Actions:
move loc x on reaver
preserve trigger

player 1 is the reaver in this case
For the killing thing

Code:

player 2,3,4,5,6,7,8

Requirements: Always

Actions: Kill any unit at loc x 

There you go, good luck :yes:

 

well... there are two problems...

1.

Code:

player 2,3,4,5,6,7,8

Requirements: Always

Actions: 
Kill any unit at loc x
[b]Preserve Trigger[/b]

and
2.

if you have other Wait conditions, they will be ignored

 

This alone won't do it; what will happen if you do it this way is when the level starts the trigger will fire once and kill the reaver.

Here are two ways you could do what you want.

Code:

Way #1 -  one trigger

CONDITIONS
 - Always
ACTIONS
 - Center Location 1 on Reaver for Player 2 at anywhere
 - Kill all Zergling for Player 1 at Location 1
Preserve Trigger

Code:

Way #2 - two triggers

CONDITIONS
 - Always
ACTIONS
 - Center Location 1 on Reaver for Player 2 at anywhere
 - Preserve Trigger

CONDITIONS
 - Player 1 brings a Zergling to Location 1
ACTIONS
 - Kill all Zergling for Player 1 at Location 1
 - Preserve Trigger

The first way is more concise, but Ursawarrior is right: any time you have a trigger firing repeatedly, it can slow down other triggers trying to fire at the same time. Depending on the specifics of your map, this might be avoidable.

First, is the Reaver moving or stationary? If he's sitting in place (if he's a neutral unit, for example, or if the Zergling is invincible, or if you're using a structure rather than a Reaver), you don't need to move the location at all--just place it over the Reaver in the editor.

Second, setting up the kill trigger (the second one in Way #2, above) to trigger on the Zergling entering the location rather than "Always" (which is shorthand for "every 2 seconds") means you avoid most of the kind of delays Ursa was talking about. If the Zergling can't possibly die this way more than once--if you're not implementing extra lives or the ability to make more Zerglings--then you can get rid of the Preserve Trigger in that trigger all together.

Hope this helps!
