Dynamic Knock Back Force Based on Collider Velocity
I'm making a game prototype in Godot. My player character is a ship that moves around in 3D space without gravity. I have some simple code that adds a knock back force to the player on collisions ...

Rigidbody Simulated vs Static vs none
I am confused about the usage of static / not simulated rigidbodies.
I get that it is better to disable simulated to temporarily stop a rigidbody rather than deleting and recreating it, especially ...

Predictive Aim to shoot a moving target with a constant velocity while the projectile is affected by gravity (2D/Platformer view)
I've been working on creating stationary gun turrets that can shoot down missiles in my game. The bullets are affected by gravity while the missile moves in a linear path at a constant rate as if it ...

Why do my entities have jittery movement, where their velocities fluctuate wildly between frames?
I'm writing my own simulation for some robots. I want to utilize friction, acceleration, velocity calculations.
Currently, my code looks like this:

How can I constrain a RigidBody ball to move along a path, but only apply forces to keep the ball on the path without adding velocity?
I'm currently working on a game and I'm hung up on this particular issue.
I have a ball that is a RigidBody. The RigidBody is ...

Inconsistent results from ApplyCentralImpulse with RigidBody2D
I'm working on a 2D top-down game using RigidBody2D for the player and enemies. They're bouncing and moving (using ApplyCentralForce) and detecting collisions just fine, however now I want to add a ...

Applying impulses simultaneously at each contact point or sequentially?
I'm coding a 2d physics engine in python, and I'm struggling to understand the right way to implement collision resolution when there are multiple contact points.
Consider a very simple collision case ...

How can I implement actor velocity / acceleration with fluid changes if direction changes are small, and abrupt if the direction changes are large?
I hope the question title makes sense. I haven't been able to google for an answer because I don't know what the correct terminology I'm looking for is.
Basically, I have an actor / enemy / game ...

Is it possible to design character movement system with Bezier Curves?
For context, I'm trying to create a really dynamic and fast character. That can suddenly move slow, fast, zap into places, dash, and hover in place.
Say that I want to make a character accelerate a ...

Moment of inertia of an arbitrary grid of squares with different masses
I'm making a game where the player can create a 2D spaceship, one square "tile" at a time.
In order to simulate the kinematics of the ship I need :
To compute the CoM vector. That's easy ...
