Overview
The Spark Core comes with ode4j (rigid body physics library), KStateMachine (kotlin state machine library), and the bedrock version of the model animation loader and controller.
What can it do?
- It brings physics threads that can be integrated into the mc environment, which you can use to create powerful physics collision detection or to simulate realistic rigid body physics collision scenarios.
- For entities, we provide an excellent bedrock model and animation loader, you can use the bedrock model as your own entity model or a model of anything, and the model data can be read on the server side, you can call the rotation and other parameters, and also with the physics threads to simulate the physics effects in the model itself!
- Of course, we also bring some practical methods, including state machines, preset animations (e.g. state animations such as walking and running) …… There are more features for you to explore!
You can also take a brief look at our features in these videos below:
