How do I fix objects “popping” or jittering in physics engine?
I've got a simple physics engine that solves collisions by simply correcting the position of overlapping bodies (just circles for now) directly, as opposed to just changing the velocity or applying an ...

Bullet physics: how to make a soft body “static” (kind of)?
I'm fairly new to Bullet and started using it a week ago. I mainly played with rigid bodies and everything works as expected but now that I also need to add soft bodies into my simulation, things got ...

Realistic 2D Planetary Physics Engine?
I'm doing a spaceflight simulator in C++ (using Allegro 5), and I realised that I could just use a physics engine instead of writing my own physics.
So that's what I'm doing.
Since this is going to ...

Moving Sprite With Physics Frame
Normally, a physics frame in pink (see image below) gives the body for detecting hit signal. It usually either falls down or lifts up depending on the gravity orientation. The question is: Is it ...

Pick and Drop the Ball Testing Without Replicating the Physics Frame
I am making a program that pick, drag, and drop the ball. In real life, once you pick the ball and drop it, whenever the available object is (what you see is what you get) will only be picked and ...

limiting jump forces to achieve a maximum jump height [duplicate]
A player and the world are modeled using a physics engine. Jumping is modeled by applying a vertical upward force to the player's physics body when the jump button is pressed.
The upward force is ...

Resolving a collision with forces
In my 2D physics engine, I can detect AABB vs AABB collisions, and resolve them by finding the shortest penetration vector and adding it to the AABB's position.
Doing this "pushes" the first AABB ...

how to make virtual environment consistent in networked applications?
I have a Virtual Environment(grid of cubes) which has the same state on both users when the application starts.
Both users have haptic devices, whose position is depicted by a small sphere in the ...

An “AABB Physics Engine” [closed]
I've been working on the physics for my 2D game and for the past two weeks it's been doing my head in. I wanted something a little more complicated than what you see in 2D platformers, but I wanted to ...

Friction due to gravity in an impulse based physics engine
In my physics engine, i'm using impulses to solve collisions. I'm basing all calculations on these equations:
impulse = desired_velocity_change * mass
impulse = force * time
friction_force <= ...

What physics engine support force fields and bodies represented as points?
I need a game engine that supports force fields in 2d or 3d, but suitable for 2d calculations, like bullet.
Each body I want to simulate is represented as a set of points. Each point has positive ...

RK4 integration and Continuous Collision Detection
I'm using this method to detect collision between two AABBs. The algorithm is simple, fast and works great. It uses the relative velocity between the two objects to calculate TOI. This works fine with ...
