Add Remove Model

Adding model

// Spawn a new entity
Pig pig = location.getWorld().spawn(location, Pig.class);
// Create a new ModeledEntity from the spawned entity
ModeledEntity modeledEntity = ModelEngineAPI.createModeledEntity(pig);
// Create a new ActiveModel using the ID of a model
// Will throw an error if the model does not exist
ActiveModel activeModel = ModelEngineAPI.createActiveModel("test_model");
// Add the model to the entity
modeledEntity.addModel(activeModel, true);

Removing model

// Grab the ModeledEntity instance associated with the entity
// Can also use entity ID or entity UUID
ModeledEntity modeledEntity = ModelEngineAPI.getModeledEntity(pig);
// Remove the model
modeledEntity.removeModel("test_model");
