I've done some basic 1 D integration, but i can't wrap my head around things and apply it to my graph layout. So, consider the picture below:

if i drag the red node to the right, i'm forcing his position to my mouse position
the other nodes will "follow" him, but how ?

For Verlet, to compute the newPosition, i need the acceleration for every node and the currentPosition. That is what i don't understand.

How to i compute the acceleration and the currentPosition ?

The currentPosition will be the position of the RedNode ? If yes, doesn't that means that they will all overlap ?

I have implemented a physics engine based on the concepts in the classic text Advanced Character Physics by Thomas Jakobsen. Friction is only discussed very briefly in the article and Jakobsen himself notes how "other and better friction models than this could and should be implemented." Generally… >>> More

I am modeling walking insects. I implement them as cuboids and use forces (including friction and drag), to control motion. However, the movement characteristics of this 'sliding box' physics don't match those due to a legged creature. For example, legged creatures near-instantly accelerate to… >>> More
Sharing data between graphics and physics engine in the game?

I'm writing the game engine that consists of few modules. Two of them are the graphics engine and the physics engine. I wonder if it's a good solution to share data between them? Two ways (sharing or not) looks like that: Without sharing data GraphicsModel{ //some common for graphics and physics… >>> More

If anybody has dealt with a similar situation I'd be interested in your experience/wisdom, I'm developing a 2D game library in C++, I have game objects which have very basic physics, they also have movement classes attached to differing states, for example, a different movement type based on whether… >>> More

Good afternoon, Is there a way to split data from one row and store to separate rows? I have a large file that contains scheduling information and I'm trying to develop a list that comprises each combination of course, day, term and period per line. For example I have a file similiar to this: Crs:Sn… >>> More

I've been trying out some rope-physics recently, and I've found that the "standard" solution - making a rope from a series of objects strung together with springs or joints - is unsatisfying. Especially when rope swinging is relevant to gameplay. I don't really care about a rope's ability to wrap… >>> More
