simple system

[Klann]

how do i add a system where if a unit gets hit by a moving vehicle, the unit dies.

how can i do this with triggers and without any skills?

 

[puggsoy]

LOL, when you said without any skills at first I thought you mean "without being skillful" XD

Well, how about you check out this thread. If you want to use only triggers then you could try defskull's suggestion, however I personally think I would use TLI-Inferno's method. That way you can just add the ability to the vehicle(s) you want.

Well, whatever method you choose, I hope it works.

 

[defskull]

Of course TLI's suggestion has greater potential for that thread because the thread starter wanted that if Unit A walks in a straight line, every enemy of Unit A (this is conditions, this is for you to decide) will be killed if it gets too close to Unit A

That's not a "detecting collision system", it just kills any nearby unit (your condition)

With my system, you can do whatever you want with the collided units

Conclusion:
TLI System: Detect to kill
My System: Detect to do whatever you want to the detected unit

+ he asked how to do it with triggers, not abilities, so defskull's method would be the only solution in this case.

I do suggest you remove the event of defskull's trigger and then do this for every vehicle:

• Trigger - Add to Some Trigger the event (Unit - A unit comes within 150.00 of Vehicle)

You don't need the timer for that (running a trigger every 0.03 seconds is slightly more demanding) and it doesn't have the potential to leak a location and a group.
Of course, you can't edit the range in this case, nor can you easily get the vehicle.

@ap0calypse

Try moving a unit behind the vehicle while it's idle =P
LOL That'd be funny.
I'm writing this system right now

Oh, right... a /moving/ vehicle...

Well, in that case: if you want to do it correctly, you'll need some math to check whether the unit is actually in front of vehicle too ^^
Simple stuff though, nothing too fancy.

 

[defskull]

Talk about "reality system" ...
I'm surely ap0's trigger would do fine since this trigger is used in Maze Map where you have to evade an incoming cars and stuffs LOL

I wrote this library:

library CarAccident
    globals
        private constant integer OFFSET = 0x100000 // DONT EDIT
    endglobals

            call BJDebugMsg("Checking")

But it's not working >.<
yeah... I'm lifeless =P

i don't use jass since my WE doesn't work on newgen

the thread works but i changed the collision from 160 to 110 making the system work only for moving units. but there is also a problem, if the unit was the one to charge the vehicle it still gets killed ^^

 

[puggsoy]

Try changing this line:

• Unit - Kill (Picked unit)

To this:

• If ((Owner of (Picked unit)) Equal to Player 2 (Blue)) then do (Unit - Kill (Picked unit)) else do (Do nothing)

That is of course, assuming that the enemy is Player 2 (Blue). If not, just change the Player there to the owner of the units you want to be killable. Then it won't kill your own units, which, as I understand, was your problem.

Of course TLI's suggestion has greater potential for that thread because the thread starter wanted that if Unit A walks in a straight line, every enemy of Unit A (this is conditions, this is for you to decide) will be killed if it gets too close to Unit A

That's not a "detecting collision system", it just kills any nearby unit (your condition)

With my system, you can do whatever you want with the collided units

Conclusion:
TLI System: Detect to kill
My System: Detect to do whatever you want to the detected unit

I knew Klann would use your method since he wanted it with triggers only, but even so, if I were in his position and I didn't mind using skills I would use TLI's method, since what he also wants to kill the unit. Obviously, if I wanted to do anything other than kill them I would use your method.

 

[Klann]

Changing this line :

• Unit - Kill (Picked unit)

To this :

• If ((Owner of (Picked unit)) Equal to Player 2 (Blue)) then do (Unit - Kill (Picked unit)) else do (Do nothing)

will prevent killing my own units. but isn't this prevents a friendly/allied unit from getting killed by this system? (this was already in the test map)-->

• Unit Group - Pick every unit in (Units within 160 of UnitPoint (((Matching unit) belongs to an enemy of (Owner of Unit) Equal to True)) and do (Actions)

 

[puggsoy]

What it does is it only kills units that are owned by the specified Player (Player 2 in my example).
What exactly is your question? Your wording was a bit strange. Are you asking if this:

• Unit Group - Pick every unit in (Units within 160 of UnitPoint (((Matching unit) belongs to an enemy of (Owner of Unit) Equal to True)) and do (Actions)

does the same? or are you asking something else?

 

[defskull]

Also, 160 is standard value for "a unit face a unit in melee combat"
This value is referred from Immolation ability.
