Deletevehicle _x

[Chris Death 0]

I ran into a problem, using deletevehicle _x, to delete a whole

group.

I've had a group, named: hosta (two resistance soldiers)

Because i was using guard wayoints for the enemy troops, i did not want to confuse by having unnecessary tropps on

the battlefield.

So after the two resistance soldier's job was done, i used the

onActivation field of their last wayoint to delete them:

"deleteVehicle _x" forEach units hosta

Unfortunately at exactly this point of the mission, the game

crashed everytime.

So i had to investigate this problem, since the syntax of the

command i've been using was correct.

After having a look into a mission, where i also have been using this command (and it did not crash the game there),

i found a little difference.

I've executed the same command, but i've been using a trigger

in this mission.

After changing the delete procedure in my other mission from

waypoint to trigger, it worked there aswell

Summary:

If you want to delete a whole group by using deletevehicle _x,

you MUST NOT use a wayoint of this group for that

!!!!! this causes your game to crash !!!!!

After thinking a little bit about it, i totally understand this problem now, because of deleting the group,

also the waypoint will be deleted, and so the whole procedure gets deleted, while executing it.

hope this is some useful information for you guys

Thanks for that.

I use an alternative solution to this. I set up a huge trigger

covering the region I want to clear. There can be waypoints, groups or whatever in this trigger area. Set the activation of the trigger to anybody. and the condition to false.

Name the trigger clearzone. Now setup a second trigger to fire a script. The trigger could be loacted at point where player leaves an area and enters a new one without turning back to first area (mission objective).

the fired script should look like this:

Code:

"deletevehicle _x" foreach list ClearZone

This way you will get rid of all units within clearzone trigger radius. No crashing here.

This i already knew Balschoiw, but what i did not

know before was: that using the command out of

the onactivation field in a waypoint of the group which

has to be deleted.

Using your method would really not have been necessary in

the mission, where i found that problem. It was only

this two men group, to be deleted.

Never mind, I have to check this out...

Good find...

Another solution is create a scripted waypoint right after the one you wanted to delete in. There just execute a tiny script (like del.sqs) that has the line </span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">"deleteVehicle _x" forEach units grp1;<span id='postcolor'> inside.

It works well.

Yeah bn880, doing it out of a script will work aswell.

As we both understood that thing the same way, you

can do it however you want, except: out of a wayoint

of the group, which has to be deleted.

Waypoints of other units or groups shouldn't matter, since

they won't get deleted during this procedure.

cheers, but i wish i could say, that there would not have

been the need to find this
