Description
- Description:
- Returns objects intersecting with the virtual line from begPos to endPos. By default, the resulting array of intersecting objects is unsorted (see sortByDistance).
- Groups:
- Math - Geometry
Syntax
- Syntax:
- lineIntersectsWith [begPos, endPos, objIgnore1, objIgnore2, sortByDistance]
- Parameters:
- begPos: Array format PositionASL - virtual line start
- endPos: Array format PositionASL - virtual line end
- objIgnore1: Object - (Optional) 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) 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: Boolean - (Optional) true: sort by descending distance (furthermost object first, closest object last); false: unsorted
- Return Value:
- Array - intersecting objects
Examples
- Example 1:
- Example 2:
- Sort by distance:
- Example 3:
- Ignore objects:
