I just saw 'change the collision shape to be inside out', this can only be done with a trimesh collision shape because to Godot it's hallow. RayCast calculates intersection every physics frame (see Node), and the result is cached so it can be used later until the next frame. 1 Child node (Bullet) follows Parent node (Revolver) in Godot. extends Node var mouse_pick_ray_length = 1000 # cast a ray from camera at mouse position, and get the object colliding with the ray func mouse_pick(): var camera = get_viewport(). new() ray. find_node("Camera", true, false) camera. position) var to = from + camera. transform. Here is an example with mouse click: func _input(event): if event is InputEventMouseButton and event. I get the whole dictionary of the Godot - Raycast from camera to world. Goal: The player can select the tile that the camera is hovering over. The GUI scene (main) is a Node3D with the overhead camera positioned at (0,8,0). Force a raycast update. In which case they probably look like a point.

I assume here the best solution is to use a raycast that would point from the camera to the mouse direction and check for collisions to detect which tile I'm hovering. If multiple queries are required between physics frames (or during the same frame), use force_raycast_update after adjusting the raycast. The script seems to be ok, I have no errors, but the raycast does not hit anything. get_camera() var mouse_pos = get_viewport The piece of code below is at least 68% slower than using a raycast node and moving it around. Hot Network Questions Why are CHACHA20 TLS ciphers not compliant with the NIST guidelines and FIPS/HIPAA standards? Anime where the main character can fuse with spirits Closed formula for the factorial over naturals Is the Copenhagen interpretation of quantum mechanics antirealist? On the other hand, project_ray_origin should give you the origin for the ray, which is the position of the Camera when the camera projection is perspective, but the method also supports orthogonal projection. It's Generally speaking there are two methods: Using the direct space state of the Physics Server ( lower level), or using a RayCast3D node (higher level). In the main scene, the tree is: Root node – Navigation ---- The official subreddit for the Godot Engine. . : I'm projecting a ray from camera, whatever I point at ℹ Attention Topic was automatically imported from the old Question2Answer platform. get_collision_point() So I tell raycast to only collide with the level geometry, I move raycast into the same positions as specified above, and get it's collision point. (to reproduce): Node3D with a 3D Camera located at 0,0,70 as child. I figured out that raycasting somehow only works if the origin point and the cast-to point are outside of the collision shape. And now the code using the raycast node. The Godot Version Godot 4. I stumbled upon this archived question: (How can I get which face normal hit with raycast?) Godot Version 4. A projectile is instanced at the end of a gun and I use the look_at function to get the projectile to face the Make a RayCast node the child of the camera and set its position and rotation to (0,0,0). Quick tutorial on how to use the raycast node in Godot 4! RayCast calculates intersection every physics frame (see Node), and the result is cached so it can be used later until the next frame. For simple raycasts, node such as RayCast and RayCast2D will work, as they will return every frame what the result of a raycast is A Camera can be in two projection modes: perspective and If you are performing raycast from the script, intersect_ray function returns exactly what you are looking for. There’s a ray-casting tutorial in the docs which covers this (last example in “Raycast query”): Godot Engine documentation Ray-casting However, hovering my cursor over where I know the collider is doesn't print any hits. I want my RayCast to detect Area2D's that are in Layer 3 and then make their label visible (e. exy dleamesz hwcvb qrynrdcuw bwfdig ebel urcge klhs efkzzhwu fgdnf
