I'm trying to write a function to handle movement within a game I'm programming. What I have nearly works, but there are a couple situations where it breaks down. I've coded up a minimal demonstra...

I have 2 rigid bodies (a & b) and 1 fix joint constraint (with relative transformation rela). My objectives are to achieve :- No. 1. b.transform = a.transform * rela No. 2. Center of mass (...

I'm working on a 2D top-down open-world game in which there is a character who can be moved by keyboard functions. The movement is caused by Rigidbody.AddForce(). The problem is that the moving spe...

I'm relatively new to asking questions here, so please bear with me. I am trying to create a top down driving game with Matter.js as the primary physics engine. I would like the red car to collide ...

After some time of "development" of the JavaScript game, I've came to a great idea, or so it seemed / sounded. I was thinking of creating an entity which would represent lava. That lava would move...

I'm a fairly new app dev and very new to Sprite Kit. I am creating a game where I want a ball to always fall downward as if it were in gravity. This is just a 2d app so all I want is when the ball ...

I'm trying to simulate a soccer game. I have a SCNPlane that simulates the court. I have imported a Soccer goal 3d model (.dae file) and also a ball model (.dae). My ball has a dynamic physics bo...

I'm not using any engine, but instead trying to build my own softbody dynamics for fun using verlet integeration. I made a cube defined by 4x4 points with segments keeping its shape like so: I h...

I code a mini Android game scenario inspired by Space Invaders and Moon Patrol. It is possible to shoot an alien horizontally (see above). It is also possible to shoot an alien vertically (see ...

Making a game using Golang since it seems to work quite well for games. I made the player face the mouse always, but wanted a turn rate to make certain characters turn slower than others. Here is h...

I am modelling a particle in 3D space. {0} The particle starts at time t0 from a known position P0 with a velocity V0. The velocity is computed using its known previous position of P-1 at t-1. ...

I'm creating a side-scrolling endless space themed game using canvas and JavaScript. I'm controlling a spaceship just by using the up and down arrows and I want to implement some kind of movement e...

So I've wrote a microbe animation. It's all cool, but I think that it would be even better, if the microbe would be able to eat diatoms, and to destroy bubbles. The issue is that the microbe is ma...

I attach a rigidbody to a HingeJoint in Unity. It's attached no at the the center of an anchor of a joint. To stop it from falling I set Use Motor = true, Target Velocity = 0 and apply some force...

I am working on some shaders, and I need to transform normals. I read in few tutorials the way you transform normals is you multiply them with the transpose of the inverse of the modelview matrix...

According to several developers (link1, link2) the proper way to have a constant frame rate with requestAnimationFrame is to adjust the "last rendered" time within the game loop as follows: functi...

So, I am currently reinventing the wheel (and learning a lot) by trying my hand at making a simple physics engine for my game engine. I have been searching the internet, trying (and failing) to fix...

So there is a problem that whenever I use Physics.OverlapBox to check how many objects in that area exist it always output 0. Here is my stripped down code: void Update () { a(); } void a() { Co...

I am trying to create custom components in Android using Surfaceview and canvas drawing. The components are re-sizable and rotatable by touching. Consider creating an image view its Top,Right,Botto...

I have pitch, roll, and yaw angles. How would I convert these to a directional vector? It'd be especially cool if you can show me a quaternion and/or matrix representation of this!

I'm creating a simple asteroids-like game in CSS and JS using the DOM over canvas for...experimentation purposes. My code is pretty small in this example to make it easy to see what's going on be...

I am programming a game using OpenGL GLUT code, and I am applying a game developing technique that consists in measuring the time consumed on each iteration of the game's main loop, so you can use ...

Have a very small snippet of an asteroids-like game I'm working on using only the DOM without Canvas. I have the "ship" moving pretty smoothly when arrow keys are pressed but how would I go about m...

I have a gravity vector (in the form [r, theta]) which I add to my ball's velocity vector. For some reason, the ball doesn't return to the same height after bouncing, but instead slowly loses heigh...

I am trying to create a chain of moving objects for a game (AS3). So far, I can drag objects behind another object, but all I can do is make a link move closer to another link based on distance. It...
