Raycast
Cast a ray from an origin in a given direction. Returns a HitInfo.
from ursina import raycast, scene, Vec3, time
hit_info = raycast(
origin,
direction=(0, 0, 1),
distance=float('inf'),
traverse_target=scene,
ignore=[],
debug=False
)- origin: start position (
Vec3) - direction: unit vector direction
- distance: max length
- traverse_target: restrict to specific entity or scene
- ignore: list of entities to skip
- debug: draw the ray onscreen
Example: only move if no wall is hit
origin = player.world_position + (player.up * 0.5)
hit_info = raycast(origin, player.direction, ignore=[player], distance=0.5)
if not hit_info.hit:
player.position += player.direction * 5 * time.dt
