hybrid steeple
I have 2 cubes that are RigidBody3D instanced from the same resource. Both of them are in Collision Layer 1 and Mask 1
They can interact with each other and push each other (even when thrown) and no issues occur there.
I have player which is also a RigidBody3D and also in Layer 1 and Mask 1.
I move the player using apply_central_force but the player's body is unable to push the cubes. And I don't see any reason for that happening.

Could you show your script and properties of your rigidbody
hybrid steeple
for cubes I'm just adding them to a group, I'm not doing anything with this group as of yet.
This is for moving player:
# Moving
if Input.is_action_pressed("move_forward"):
direction.z = -1
if Input.is_action_pressed("move_backward"):
direction.z = 1
if Input.is_action_pressed("move_left"):
direction.x = -1
if Input.is_action_pressed("move_right"):
direction.x = 1
# Capture camera rotation
var camera_rotation = camera.rotation_degrees.y
# Rotate direction based on camera yaw
direction = direction.rotated(Vector3.UP, deg_to_rad(camera_rotation))
# Movement
if direction != Vector3.ZERO:
var movement_force = (direction.normalized() * speed) * state.step * 50
apply_central_force(Vector3(movement_force.x, 0, movement_force.z))
var horizontal_velocity = Vector2(linear_velocity.x, linear_velocity.z)
if horizontal_velocity.length() > max_speed:
horizontal_velocity = horizontal_velocity.normalized() * max_speed
linear_velocity.x = horizontal_velocity.x
linear_velocity.z = horizontal_velocity.y
else:
# Movement damping
linear_velocity.x *= movement_damping
linear_velocity.z *= movement_damping```

Is this script in process or physics?

Is this script in process or physics?
_integrate_forces
feral notch
`_integrate_forces`
If you're already using integrate_force. What is the need to call apply_impulse?

You mean apply force?
Well... how do I move the player otherwise?
feral notch

linear_velocity
hybrid steeple
linear_velocity
Well it doesn't really fix the issue tho
feral notch
Try removing apply_impulse
hybrid steeple
I'm using force since it's smooth
feral notch
They are both acting on the same bodies so they might be conflicting each other. Although not sure but could be
feral notch
I'm using force since it's smooth
To make it smoother you can use move_toward.
That also smooths the change
hybrid steeple
I tried with applying constant force to one cube, and it pushed the other, so it's something else.

In that case was applying_constant_force the only part that was applying force?
hybrid steeple
yes, I didn't touch the cube, stand in its way or anything. I just set the constant force in properties and watched

Cube is the other rigibodies which the player is trying to push, right?
hybrid steeple
Yep. They are the same resource, just instanced. Player is different scene obviously :P
feral notch
Well then I don't understand the use of this. What was the point of that? Isn't the problem that player is unable to push other cubes?
hybrid steeple
The problem is that while 2 cubes are same layer, same mask, they are able to interact with each other
but if the player is the same layer and same mask as the cubes, the player's body is unable to push the cubes.
No matter what force I apply, they don't even budge
feral notch
In that case try removing the apply_impulse part from the script
let the linear_velocity move the player
I am not saying that this is the solution.
I just want you to try, as this could be a reason
hybrid steeple
I tried that - I added velocity via properties and didn't press anything (I left the code as-is).
Collided with the cube but didn't move it
I can edit code I guess
hybrid steeple
No problem, thanks for the help anyways, I have 0 idea why this is the case.
feral notch
Hmm
Try commenting out the whole part setting linear_velocity
Just for test
Let the apply_impulse move the body alone
feral notch
So as it was originally?
Even in the original code you have a part setting linear velocity
I want you to comment those out
Don't let linear velocity interfere
hybrid steeple
ah yeah, okay one sec
feral notch
For the player?
Yes in the player
hybrid steeple
nope, same thing
The thing is, it's not mass of the cubes as well - they just behave as if they were static
hybrid steeple
super?
feral notch
Just for test
hybrid steeple
I never used super, do I call it before func declaration?
feral notch
I never used super, do I call it before func declaration?
No, you call it within a function
Super just called the same function of its parent
So like if _integrate_force has any functionality that you override. It will call that
hybrid steeple
Line 52:Cannot call the parent class' virtual function "_integrate_forces()" because it hasn't been defined.
feral notch
A wasted effort😅

Did you try adjusting bounce on the material?
hybrid steeple
on the player material - yeah, but I'll try on the cube
feral notch
on the player material - yeah, but I'll try on the cube
Player won't need it, the cubes could
hybrid steeple
well I bounce off the cube but the cube won't move
hybrid steeple
I tried that haha, but good luck
feral notch
I tried that haha, but good luck
Just for reference, see the player is able to push the body without a script.
sleek flume
So my first thought is, strip the player to a regular rigidbody then drop it on a box and see if it moves
feral notch
That'll narrow out the reasons
feral notch
So my first thought is, strip the player to a regular rigidbody then drop it on ...
🙄
We said the same thing
😅
hybrid steeple
Aight one sec, I'll detach the script
Uhh one sec I gotta figure out the camera part x)
sleek flume
(My second thought is, are the boxes sleeping, but if bumping one into the other works then thats probably not it. Still worth turning sleeping off on them just to check)
hybrid steeple
nope not sleeping, one sec
sleek flume
(Third thought is, maybe the force is just too small to budge 'em, so make the player move at super speed)
feral notch
(Third thought is, maybe the force is just too small to budge 'em, so make the p...
But the player is able to move so its not small
hybrid steeple
the thing is, even a tiny bump cube to cube makes them move. Not super crazy but you can clearly see
even if I throw
sleek flume
Could be it can overcome its own friction but not that + the boxes. But unlikely, yeah
feral notch
the thing is, even a tiny bump cube to cube makes them move. Not super crazy but...
So did you strip the player of its script?
hybrid steeple
yep one sec, placing another camera
nope, nothing, the cube doesn't even move a tiny bit
Now this is super weird.
I'll make player super heavy and drop it from far above, one sec
okay well, 5000 KG was enough to push cube into the ground.
huh is it really the weight issue....
I'll attach the player script and try with the same mass
ye, it's mass....
But then again, what the hell is the rule here, why does player needs to weight 5000 kg and have a push force of a Hulk to push a 1kg cube?
oh for #@%# sake
this is my cube script...
Sorry guys, I am apparently blind :)
