Description
- Description:
- Checks for object intersection with a virtual line between two positions.
- 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
