Description
- Description:
- Returns objects intersecting with the virtual line from begPos to endPos. By default resulting array of intersecting objects is unsorted. To sort by distance set sortByDistance param to true.
- Groups:
- Math - Geometry
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];
