Gravity Simulation failing at short distances
I have a 2D space simulation with gravity acting on three bodies (e.g. sun and 2x planets). The simulation seems pretty stable with RK4 (was unstable with Euler). The problem arises if the orbit of ...

Preferred way to integrate box2d with SFML
I'm trying to integrate Box2D with sfml. My current solution is to have overloaded functions creating sfml shapes from box2d fixtureDef shapes. I store created sfml shapes under the name 'visual' in a ...

Working out velocity/time based on physical pixels moved
In my game I integrate like so: (Please assume all variables to be declared)
sprite.xTimeInSeconds = 5.0; //Time in seconds it should take this object to cross screen
sprite.xVelocity = ...

What is the purpose of integration in physics engines?
All online resources seem to assume that you know what this means and/or state that this is related to object movement in some way.
How does this differ than just position.x++ and position.y++ and ...

Understanding constant acceleration in terms of game physics simulation
There are various integration methods that can be used for games. I am trying to write a simple physics engine deciding between semi-implicit Eular and Verlet variants.
What I don't understand is ...

How do I translate accelerometer readings into object movement?
I am using the DeviceMotionEvent web API, which gives me a device's acceleration split up into x-, y- and z-dimensions and a time interval.
Here's my attempt at moving an object on screen based on ...

Integration error in high velocity
I've implemented a simple simulation of two planets (simple 2D disks really) in which the only force is gravity and there is also collision detection/response (collisions are completely elastic). I ...

Why is RK4 better than Euler integration?
At the end of these great slides, the author compares all the different integrators presented. One way or another, they all fall short except for Improved Euler Integration and Runge Kutta 4 ...
