Action on entering vehicle

[calo_mir 10]

I've created an object with createVehicle and then attached it to a unit. The unit enters a vehicle. The object stays fixed in place, floating outside. If the vehicle drives away, the object stays where it was when the unit entered.

Without adding an event handler to every single vehicle that the unit might possibly enter (including remembering to add one for every vehicle that might be created via a script), is it possible to have some code executed when a unit enters a vehicle?

I'd like to hide the attached object temporarily, whilst the unit's in the vehicle. Alternately, I'll attach the object to the vehicle and then reattach it to the unit when it exits.

The reason I don't want to create an event handler for all vehicles is because I'm intending to create a reusable script and it's unreasonable to expect the user of that script to fiddle with all the vehicles in their scenario in that way.

You could check if the player is in a vehicle with this:

if (!((vehicle player)== player)) then {....

Certainly, yes. The problem is knowing when to call it. I could call it periodically on all players with attached objects, but that's likely to be expensive and not exactly very pretty...

wrong post.

Not exactly what you asked, but here's a method I used in a mission to have an action available for the player, on foot or in any vehicle.

while {true} do {
 waituntil {vehicle player == player};
 if (!isnil "_veh") then { _veh removeaction _id };
 _id = player addAction ["ActText", "script.sqf",[],1,false,true,"",""];

 waituntil {vehicle player != player};
 player removeaction _id;
 _veh = vehicle player;
 _id = _veh addAction ["ActText", "script.sqf",[],1,false,true,"",""];
};

Ah, yeah, I see. I didn't grasp what you meant at first.

Not a bad idea. I'd expect people to register their units with my script (it's essential for the type of game it manages anyway). I'd spawn one process per unit that keeps an eye on their vehicle usage.

Thanks, I'll try this.

as for hiding the object this works quit well

just have a trigger set up

on act player in vehicle

cond object hideobject true

then another trigger

on act !(player in vehicle)

cond object hideobject false

But only with the beta patch. 1.05 hasnt got the hideObject command. 1.06 will have it.

E: with version 1.05 use deleteCollection

but this wont work with the beta patch or 1.06

Suspect I'll be checking the running version at runtime...

Good point I'd forgotten about that.

I'm not sure about deletecollection how do you restore it?

You cloud just delete the object and respawn it in the second trigger.

Seems theres no way to restore that. But whats about detach the object, moving it to [0,0,0] and then attach it again? of course only if you cant use hideObject.

or this.
