classmethod get_trajectory_sample_at_time(trajectory, time, extrapolate=False) → PoseSearchQueryTrajectorySample

Get Trajectory Sample at Time

Parameters:

• trajectory (PoseSearchQueryTrajectory) –

• time (float) –

• extrapolate (bool) –

Returns:

out_trajectory_sample (PoseSearchQueryTrajectorySample):

Return type:

PoseSearchQueryTrajectorySample

classmethod handle_trajectory_world_collisions(world_context_object, anim_instance, trajectory, apply_gravity, floor_collisions_offset, trace_channel, trace_complex, actors_to_ignore, draw_debug_type, ignore_self=True, max_obstacle_height=10000.000000, trace_color=[1.000000, 0.000000, 0.000000, 1.000000], trace_hit_color=[0.000000, 1.000000, 0.000000, 1.000000], draw_time=5.000000) -> (out_trajectory=PoseSearchQueryTrajectory, collision_result=PoseSearchTrajectory_WorldCollisionResults)

Experimental: Process InTrajectory to apply gravity and handle collisions. Eventually returns the modified OutTrajectory. If bApplyGravity is true, gravity from the UCharacterMovementComponent will be applied. If FloorCollisionsOffset > 0, vertical collision will be performed to every sample of the trajectory to have the samples float over the geometry (by FloorCollisionsOffset).

Parameters:

• world_context_object (Object) –

• anim_instance (AnimInstance) –

• trajectory (PoseSearchQueryTrajectory) –

• apply_gravity (bool) –

• floor_collisions_offset (float) –

• trace_channel (TraceTypeQuery) –

• trace_complex (bool) –

• actors_to_ignore (Array[Actor]) –

• draw_debug_type (DrawDebugTrace) –

• ignore_self (bool) –

• max_obstacle_height (float) –

• trace_color (LinearColor) –

• trace_hit_color (LinearColor) –

• draw_time (float) –

Returns:

out_trajectory (PoseSearchQueryTrajectory):

collision_result (PoseSearchTrajectory_WorldCollisionResults):

Return type:

tuple
