Direction Question

[angusjm]

How do you check if a unit is pointing a certain direction?

I want a condition for a trigger that will only activate if a unit is facing between certain angles.

[macguba]

the command you want is

getDir object

returns a number between 0 and 360

eg put in the condition field

175 <= getDir medic1 <= 185

As ever, I direct you to the un+official command refs in the Editors Depot for more info.

What if you don't know the name of the unit, you want to get the direction of any unit that enters the trigger area?

The azimut can be -53 as well as 307, it doesn't matter  

...a bit like... nah, nevermind about that   ;D


*cough* uuum,   ya dunno the name of the guy?! May we guess? howsabout... "BOB"   ;D

 j/k, check this out, m8   :wow:



Trigger (cond. field of horror-codes) :


"Getdir _X >= 230" Count ThisList >0  

This trigger would fire (I believe) if some moron (anyone) was inside the
radius and had an azimut of 230 or above!

An exact direction check would be == instead of >=   But it's unrealistic to hope for that;
imagine a guy looking EXACTLY at 230 degrees  ;D man, you'd have to wait for that trigg to fire!!!

Thus, I'd suggest something like this:

"Getdir _X >= 230" Count ThisList >0 && "Getdir _X <= 290" Count ThisList >0

This way, the trigger will ONLY fire if a d00d walks into it and turns his
fat head in some direction between 230 and 290  

(off course, ya can just change those #s to yer delight)


--------------------
Just a sidenote here :  ya wouldn't be working on a "detection" trigger, oy  
coz if so, use "knowsabout" - thats more realistic   ...oh well, yer call.

That works Great!  

The only problem is - what if I want it to go if the guy is pointing between 350 and 10 degrees?  That means that it goes through 0 degrees, so how would I do it?

"Getdir _X >= 350" Count ThisList > 0 OR "Getdir _X <= 10" Count ThisList > 0
