Description

Description:
Checks for object intersection with a virtual line between two positions.
  • Does not work under water.
  • Max harcoded distance is 1000m.
Groups:
Math - Geometry

Syntax

Syntax:
lineIntersects [begPos, endPos, objIgnore1, objIgnore2]
Parameters:
begPos: Array format PositionASL
endPos: Array format PositionASL
objIgnore1: Object - (Optional, default objNull) object to ignore. When testing intersection from an object/unit/vehicle, pass that object here to prevent intersection inside of the object
objIgnore2: Object - (Optional, default objNull) 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 an intersection happens with an object (not with terrain)

Alternative Syntax

Syntax:
lineIntersects [element1, element2, ...]
Parameters:
elementN: [begPos, endPos, objIgnore1, objIgnore2]
  • begPos: Array format PositionASL
  • endPos: Array format PositionASL
  • objIgnore1: Object - (Optional, default objNull) object to ignore. When testing intersection from an object/unit/vehicle, pass that object here to prevent intersection inside of the object
  • objIgnore2: Object - (Optional, default objNull) 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:
Array format [element1 result, element2 result, ...] - true if an intersection happens with an object (not with terrain) for the Nth element

Examples

Example 1:
private _hasStraightLineToChopper = lineIntersects [eyePos player, aimPos chopper, player, chopper];
