Why does my RigidBody3D barely move?

linear_damp at default 0.1 isn't crippling, but a value of 1+ removes velocity each tick. Check linear_damp; for free movement, set 0. Angular damp similarly affects rotation.

Should I set velocity in _process or _physics_process?

_physics_process or use _integrate_forces. Setting in _process applies inconsistently across physics ticks; the integrator overrides on the next physics step.

What's gravity_scale?

Multiplier on gravity. 1 = normal. 0 = no gravity. For projectiles, set lower; for floaty platformers, lower further.

Fix: Godot RigidBody3D Velocity Clamped Tiny

Quick answer: linear_damp = 0. Set velocity in _physics_process or _integrate_forces. Confirm gravity_scale non-zero for falling.

You set linear_velocity to (10, 0, 0). Body inches forward. Linear damp eats the velocity each step.

The Fix

extends RigidBody3D

func _ready():
    linear_damp = 0.0     # default 0.1 ok; 1+ kills
    angular_damp = 0.5
    gravity_scale = 1.0

func _physics_process(_d):
    linear_velocity = Vector3(10, 0, 0)   # sticks per tick

Or use _integrate_forces for full PhysicsDirectBodyState control. Damp at 0 means no friction; combine with collisions for natural slowing.

Verifying

Body travels at intended speed. Walk back damp to 0.5: gradual deceleration. Set damp to 5: barely moves — reproduces the bug.

“Damp low. Physics tick. Velocity holds.”
