classmethod draw_trajectory(world_context_object, trajectory, debug_thickness, height_offset) → None

Draw Trajectory

Parameters:
classmethod get_trajectory_angular_velocity(trajectory, time1, time2, extrapolate=False) → Vector

Get Trajectory Angular Velocity

Parameters:
Returns:

out_angular_velocity (Vector):

Return type:

Vector

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

Get Trajectory Sample at Time

Parameters:
Returns:

out_trajectory_sample (PoseSearchQueryTrajectorySample):

Return type:

PoseSearchQueryTrajectorySample

classmethod get_trajectory_velocity(trajectory, time1, time2, extrapolate=False) → Vector

Get Trajectory Velocity

Parameters:
Returns:

out_velocity (Vector):

Return type:

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:
Returns:

out_trajectory (PoseSearchQueryTrajectory):

collision_result (PoseSearchTrajectory_WorldCollisionResults):

Return type:

tuple

classmethod handle_trajectory_world_collisions_with_gravity(world_context_object, trajectory, starting_velocity, apply_gravity, gravity_accel, 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, GravityAccel 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:
Returns:

out_trajectory (PoseSearchQueryTrajectory):

collision_result (PoseSearchTrajectory_WorldCollisionResults):

Return type:

tuple
