⚠

Doesn't work under water. Max hardcoded distance is 1000m.

Syntax

Syntax:

lineIntersectsWith [begPos, endPos, objIgnore1, objIgnore2, sortByDistance]

Parameters:

[begPos, endPos, objIgnore1, objIgnore2, sortByDistance]: Array

begPos: PositionASL - virtual line start

endPos: PositionASL - virtual line end

objIgnore1: (optional) Object - object to ignore. When testing intersection from an object/unit/vehicle, pass that object here to prevent intersection inside of the object.

objIgnore2: (optional) Object - another object to ignore. When testing intersection of a line between two objects, pass the second object here to prevent intersection inside of it being reported

sortByDistance: (optional) Boolean - true: Sort by distance => furthermost object first, closest object last; false: unsorted

Return Value:

Array - intersecting objects

Examples

Example 1:

_objects = lineIntersectsWith [eyePos player, AGLtoASL screenToWorld [0.5,0.5]];

Example 2:

Sort by distance: _objects = lineIntersectsWith [eyePos player, AGLtoASL screenToWorld [0.5,0.5], objNull, objNull, true];

Example 3:

Ignore objects: _objects = lineIntersectsWith [eyePos player, aimPos chopper, player, chopper];
