Check for distance between flying plane and marker

[wiggum2 31]

Hi !

I try to do a HALO script and i need to check for the distance between the flying plane and a marker.

((_plane distance getmarkerpos _dropPos) < 150)

But this does not work, with vehicles and helicopters it works but the the condition never returns true with a plane although the plane is close enough.

I know that getMarkerPos always returns 0 for z but is this really the problem ?

Is there any other way to check for distance between a flying plane and a marker ?

Thanks !

1. use -showScriptErrors

2. try:

_markerPos3d = (getmarkerpos _dropPos) set [2, 0];

((_plane distance markerPos3d) < 150)

[demonized 20]

distance reads direct line from position to position, if a plane is 150 up there is a big chance of the check never activates since plane needs to be in perfect position above marker to be within. Just a little too the left or right or up and it never activates, try exstending range and check again.

No need to add in z value in getMArkerPos.

object distance markerPosition works just fine, at least in A2 CO 1.59 no betas.

There is a function to query the distance in 2D to avoid the height problem. I don't recall the syntax now but I will add the codeline to this post later today.

EDIT

_mydistance = [x1, x2] call BIS_fnc_distance2D;

Measures the line of sight distance between x1 and x2. Works fine, I am using this in some HALO scripts. You need to have the function manager present on your game map though.

Simply use the 2D position of the plane:

(([position _plane select 0,position _plane select 1,0] distance getmarkerpos _dropPos) < 150)
