Description

Description:
Checks for object intersection with a virtual line between two positions. Returns true if intersects with an object.

NOTE: Doesn't work under water. Max harcoded distance is 1000m.
Groups:
Math - Geometry

Syntax

Syntax:
lineIntersects [begPos, endPos, objIgnore1, objIgnore2]
Parameters:
[begPos, endPos, objIgnore1, objIgnore2]: Array
begPos: PositionASL
endPos: PositionASL
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
Return Value:
Boolean - true if intersection

Examples

Example 1:
lineIntersects [eyePos player, aimPos chopper, player, chopper]
