Collision detection

[ADNORM]

I am working on a unit ability for knights that allows them to trample ground units, but I have encountered two problems:
1) I turned off collision for the knights so that they walk through instead of around other units, but I want them to still treat walls as solids.
2) I am having trouble detecting collision from the front only. When a knight passes to the side of a unit it shouldn't kill it.

I haven't given much thought to problem #1, but here's what I have so far for #2:

Trample:
     Events
          Unit - A unit comes within 128.00 of Knight 0000 <gen>
     Conditions
    And - All (Conditions) are true
        Conditions
            (Entering unit) Not equal to Knight 0000 <gen>
            ((Angle from (Position of Knight 0000 <gen>) to (Position of (Entering unit))) Greater than or equal to ((Facing of Knight 0000 <gen>) - 15.00)) and ((Angle from (Position of Knight 0000 <gen>) to (Position of (Entering unit))) Less than or equal to ((Facing of Knight 0000 <gen>) + 15.00))
     Actions
    Unit - Kill (Entering unit)

For those of you too lazy to scroll to the right, the condition specifies that the angle between the knight and the entering unit be between +15 and -15 of the knights facing angle.

The problem I still have is that the trigger only kills the unit sometimes, other times the knight walks right through them and they dont die. Any thoughts?

Well you dont need that all there, conditions are 'ALL' by default. Why 15? 30 degrees of death? This probrably wont solve the problem but change it to 22.5 so its 45 degrees

I think you can remove "(Entering unit) Not equal to Knight 0000 <gen>
" but im not sure. Is there only one knight? Or are you going to make it so any knight can do that?

1. Have you tested if they walk though walls? Well even colision 0 isnt no colsion...there is a mathamatical singurlarity they occupy even though its realy tiny... so a long object should still stop them.
2. well... it may just be that no dection system is perfect and you are going to need to live with it... my idea is to make the area bigger so theres more space for the unit to die in and mabey that will help, 30 degrees is small.

Good call!

I'm still having trouble keeping the knight from going through a wall though (I didn't actually set collision to 0, i turned it off completely with a trigger), I also don't think it should go through other knights. I'm probably going to use the action:
If (Entering unit not equal to knight) AND (Unit type of Entering unit not equal to structure)
Then- kill Entering unit
Else- Turn collision off for knight0000
the problem will be, when should I turn collision back on?
also, trees are not units, so knights could still run through those

why did you set collosion to 0? since any unit it "tramples" is dead before it gets to it, it already will go right over it.
