unreal.RigUnit_LineTraceByTraceChannel

class unreal.RigUnit_LineTraceByTraceChannel(start: Vector = Ellipsis, end: Vector = Ellipsis, trace_channel: TraceTypeQuery = Ellipsis, hit: bool = False, hit_location: Vector = Ellipsis, hit_normal: Vector = Ellipsis)

Bases: RigUnit

Performs a line trace against the world and return the first blocking hit using a specific channel. Target objects can have different object types, but they need to have the same trace channel set to “block” in their collision response settings. You can create custom trace channels in Project Setting - Collision.

C++ Source:

  • Plugin: ControlRig

  • Module: ControlRig

Editor Properties: (see get_editor_property/set_editor_property)

  • end (Vector): [Read-Write] End of the trace in rig / global space

  • hit (bool): [Read-Write] Returns true if there was a hit

  • hit_location (Vector): [Read-Write] Hit location in rig / global Space

  • hit_normal (Vector): [Read-Write] Hit normal in rig / global Space

  • start (Vector): [Read-Write] Start of the trace in rig / global space

  • trace_channel (TraceTypeQuery): [Read-Write] The ‘channel’ that this trace is in, used to determine which components to hit
