Always going left..

[granQ 293]

Ok.. i will try to explain it.

What i want is to move the player 1 meter to his left, no matter what direction he is watching.

Esp if I can do this with vector, velocity would be awesome.

The true purpose is to use the math for a missile guidance system but got problem with the moving to left. (or right).

So anyone that can give me any pointers?

try http://community.bistudio.com/wiki/modelToWorld

ah, I think I get what you mean. That way I can find the "left" position of the missile and setpos it.. not as cool as using setvelocity but i guess it works :)

Will try it later :)

Oki.. i did a script, tried to use your suggestion with "modelToWorld". However i keep getting errors like: generic error #sleep 2;

So could anyone see something wrong with this?

From the biki: sleep must be called inside of a context which is interruptible, i.e. a script executed by execVM or spawn.

[granQ 293]

yeah shouldn't be that.. it starts with a fire eventhandler.. and when removed "sleep" i still get error but for something else.

I feel like the game knows its wrong but not what.. which puts me in the same position.

EDIT. Haha, seems you were right actually.. i asked my beta tester what his init was EXACTLY.. he had exec instead of execVM.

Case closed. (somewhat.. the behavior still bad of the missile but..)

Just a tip...

_missile = NearestObject [_vehicle, _ammo]; in a parallel scripts will cause you headaches once the mission gets under load. It will fail to catch the missile since it may not be executed while the missile is near enough.

Since the actual eventhandler code is a call, it is better to expand the _this parameter so that the generated object is sent as a 6th (_this select 5) element in the array.

Something like:

this addEventHandler ["fired",{_this [color="Red"][b]+ [nearestObject [_this select 0,_this select 4][/b][/color]] execVM "scripts\EH-FiredGrad.sqf"}];
