Frequently asked questions
- Can I create hinge-type constraints in the Matali Physics environment?
- Of course, Matali Physics Core offers natural constraint that can dynamically transform into any other ones. If needed, you can initialize the constraint parameters according to the hinge-type constraint and not change them later, or change following the events in the scene - all depending your needs.
- Does Matali Physics Core support native, implicit cylinder shape?
- Yes. All supported shapes are listed in the "Primitive Shapes" table in the "Advanced Rigid Body Simulation" section of this webpage.
- Can I change the size of one physics object without creating many identical shapes?
- Of course. Matali Physics Core provides full support for physics object scaling.
- Can I dynamically change size of any physics object?
- Yes. You can change the scale of physics objects, groups of physics objects as well as groups of physics objects with constraints both during creation/initialization and in real-time during simulation. Matali Physics Core is probably the only real-time 3d physics engine that offers such ready-to-use functionality.
- Does Matali Physics Core offer programmable collision events or similar functionality?
- Of course. In the group of user controllers, Matali Physics Core offers programmable controller from collision events.
- How can I modify single triangles in non-convex triangle meshes?
- Such functionality is offered by the triangle mesh controller.
- Can I build the entire physics scene as a fully dynamic and destructible?
- Yes. Matali Physics Core engine is the best solution for such scenes.
- Can Matali Physics Core handle multiple physics scenes in one game scene?
- Of course, the examples are available in Matali Physics Game.
- Can Matali Physics Core be integrated into my game engine?
- This is a very difficult question. Generally yes, it is possible, but will require, just like in case of any other physics engine, a lot of work on your side. If you want to create games immediately, a better approach is to rely on Matali Physics as a platform, port your own modules (and C++ codes) into it, and then create and publish games.
- I used Matali Physics engine before when it was in C#. Can I use code I wrote in C# in the current version for C++?
- In most cases, after minor changes, the code related to the use of Matali Physics engine in C# can be ported directly to the current version in C++.
