Raylib plugin - Mesh picking example

[Joe7M]

I extended the raylib plugin a little bit to run the shader_basic_lighting example (https://www.raylib.com/examples/shaders/loader.html?name=shaders_basic_lighting). The only part, where I struggled a little bit was the following command in the example:

// Assign out lighting shader to model
    model.materials[0].shader = shader;
    cube.materials[0].shader = shader;

Here I wrote a helper c-function to set the shader.

static int cmd_setmodelshader(int argc, slib_par_t *params, var_t *retval) {
  int result;
  auto shader = get_param_shader(argc, params, 0);
  int modelId = get_model_id(argc, params, 1, retval);
  int materialNumber = get_param_int(argc, params, 2, 0);

  if (modelId != -1 && materialNumber >= 0) {
    _modelMap.at(modelId).materials[materialNumber].shader = shader;
    result = 1;
  } else {
    result = 0;
  }
  return result;
}

The example works fine now. I am just not sure, if this is a good way to do it.

Since I need collision detection with a mesh I followed the example mesh.picking (https://www.raylib.com/examples/models/loader.html?name=models_mesh_picking)

here is now the following line:

meshHitInfo = GetRayCollisionMesh(ray, tower.meshes[m], tower.transform);

tower is a model.

Is there a better way to get tower.meshed[m] or tower.transform in SmallBASIC or should it also be done with a helper function which will return the data or which just gets the model as parameter and then do the magic in c?
