This is a very difficult problem about how to maneuver a spaceship that can both translate and rotate in 3D, for a space game. The spaceship has n jets placing in various positions and directions....

To summarize the problem(s): I have two bodies in my world so far, one being the ground, the other one being a falling box called "fallingStar". 1) I do not understand why my bullet world is not ...

I am facing a very simple problem about Triggers, but I don't see any way to solve it. I just want the OnTriggerExit function to be called when an object inside the trigger gets disabled. Here is ...

Developing with various game physics engines over the years, I've noticed that on the same machine I observe widely different results in physics simulations between runs. Most recently, the Unity e...

I'm using plane geometries as walls in a game. I'm using ray caster to provide the player from moving through them. The problem is that planes only works one way. When the player comes from the "fr...

I wonder if there is a tool that could be used for easy generation of complex physics bodies in SpriteKit. I would like to have a volume based physical bodies with polygon-type shapes. SpriteKit al...

It is hard to describe in plain text, so I recorded a GIF to demonstrate. https://public.lightpic.info/image/2B1F_582465841.gif I am currently working on a project that requires such effect. Up t...

So I am currently working on a 2D platformer game and I have realized a big issue with my collision programming. You see, to find out collisions with the player I just moved the player rect around,...

I am using Matter.js physics in an attempt to create soft bodies. I was able to create a body like this: However I am not sure if this is the "soft body" I want. It is true that this body is not...

I am working on an asteroids-like arcade game using HTML's canvas and JavaScript. I currently have a bunch of randomly generated shapes ("asteroids") with a random number of points (3, 4, or 5) and...

I'm making an pool game with cocos2dx. First, i setup the edgeBox with this parameters PhysicsMaterial(1.0f, 1.0f, 0.8f) And then these 2 balls PhysicsMaterial(1.0f, 1.0f, 0.5f) On the update func...

I am currently using Box2d, more precisely the Java port jBox2d. I have a circle that is colliding with other circles when falling (all those circles form a kind of a crank, see picture below). ...

I am building an iOS game aimed for the new iOS 7 and Sprite Kit, using emitter nodes and physics to enhance gameplay. While developing the app, I ran into a serious problem: you create your scenes...

I am seeming to have difficulty keeping my sprite nodes inside a map boundary that I have set up in the following way: I have an SKNode *enemy that moves around an SKScene by goals and behaviors co...

I'm making a little game just for fun and I got stuck making the bullets come out of the gun. In the code below, the direction of the player is a degree angle called rot. float gunOffsetX = 106, gu...

I am getting lost in how nodespace coordinates and rotation are handled in scenekit. How do I get the direction a node is facing after rotation so I can then apply force in that direction. I assu...

I have an node in space (no angular dampening, no friction, no gravity) and I apply a torque to it (20 newton meters) over 1 second. It begins to spin and will continue forever. If I apply an inver...

How to apply a friction in a Phaser.P2.body? In a Air-Hockey phaser based game. How to "turn-off the air-flow" from hockey table ?, In this example: http://jsfiddle.net/ywzmkso3/32/ // Initializ...

I'm working on a 3D tile based game and I'm using AABB collision detection. For every cube that the player is intersecting, I find the axis along which the player is intersecting the cube the least...

I believe I have come across a bug in Unity. When using Rigidbody.AddExplosionForce() on a Rigidbody with an attached trigger Collider, the force that the object feels is affected by the size of th...

I'm trying to use Bullet Physics for collision detection only. I don't need it to move any objects for me or handle rendering with callbacks. I just want to update object locations every frame and ...

I've got the linear component of collision resolution down relatively well, but I can't quite figure out how to do the same for the angular one. From what I've read, it's something like... torque =...

Is there a way to get contact force of a collision? I tried to do this by getting the velocity in the OnCollisionEnter() method. But it's giving velocity after the contact, which isn't useful to me...

There is a commonly used verlet-integration formula on the web by Johnathan Dummer, called Time-Corrected Verlet. However I've read several forum posts, that people get weird or unexpected results ...

I'm currently building a simplified Reaction Control System for a Satellite game, and need a way to use the system to align the satellite to a given unit direction in world-space coordinates. Becau...
