Holy smokes this code works. I've been looking for a way to grab physics object in game for a while now and you sir are a legend. Only problem I've noticed is that when a rigidbody is picked up it's downwards velocity is increasing while in the air, but that makes sense as we're only moving an object around.

@cent1111 Жыл бұрын

Thanks for the feedback! One way that the RigidBody problem could be fixed is that every frame, when the variable "obj" isnt equal to "null", check if obj is a rigidbody, then if it is, set its LinearVelocity property to Vector3.ZERO, Maybe ill make a video into more explanation for grabbing.

@@cent1111 wow that is significantly smarter and easier than the dumb idea I tried getting to work with linear and angular velocity being reset when the player lets go of the grab button, then trying to get a way to detect that an object is no longer being held... somehow XD. A video on grabbing RigidBody3D nodes and maybe throwing them would be a cool follow up.

it's just easy, first make var 'which is coliding' = null than check if raycast3d is coliding inside make a condition if raycast3d.get_colidier is rigdit body 3d : which coliding = raycast.get_colider which colider.global_position = holder.global_position #how to unhold the object? if input.is action just pressed("ui_accept"): which coliding = null importent notice! check the raycast have colision mask two and which colidier physic layer assain two! plz give me A like

wow, the editing makes this almost impossible to understand

I have written this, its more source - like and does not ignore collisions for rigidBodies if collider != null && (collider.is_in_group("CARRY") && collider.is_class("RigidBody3D")) && Input.is_action_pressed("carry"): obj = collider if obj: var direction : Vector3 = obj.global_transform.origin.direction_to($"../CarryPoint".global_transform.origin) var force : float = obj.global_transform.origin.distance_to($"../CarryPoint".global_transform.origin); if (force > 0.6): force = 0.6 obj.linear_velocity = obj.linear_velocity * 0.95 obj.apply_central_impulse(direction * force) if Input.is_action_just_released("carry"): obj = null

Nice, i already did this in my latest video

okay another question cause as a relative beginner I'm super interested in how you did a lot of this stuff. what is your reasoning for coding player movement the way you do? as opposed to the native characterbody scripting for it.

@ImSim_Cook 6 ай бұрын

also, in which line are you calculating gravity? I saw the variable but didn't see where it was being applied. I wanna adopt this method of coding movement but just wanted to understand it and not copy paste

@@ImSim_Cook oh actually, there is no gravity, i made a mistake whilst declaring the variables, sorry!

this is not a good character body movement script as i just made it as a simple quick, quite crappy script, so this is not a real movement you should use

@@cent1111 I gotcha! I just hate using a prewritten script. I want to dig in and actually write it all out and the idea of using something more like an array looked cool

What to do if is_in_group() not working? (I use godot 4.3)

@cent1111 Ай бұрын

it should work, it returns a boolean value

@cent1111 idk what to do, because code is working yes, but this code is ignoring, i try to pick up object on E, but nothing, i too added block what i want pick up to the group, and i write group what i want to grab, but nothing :(

my raycast3d collides with the csgcombiner i have for the floor, not the rigidbody3d box i made. Any idea why?

I know I’m just being blind and dumb so please feel free to call me both but are you/how are you doing your character controller with no camera and head nodes?

@cent1111 6 ай бұрын

oh actually, instead of rotating the camera, for the sake of a simple fast script, i just rotate the entire player, whilst the camera is looking forward inside of the player

@@cent1111 makes total sense! However I didn’t even see a camera node in the scene tree. Was that just later on?
