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]
