Model won't render in my XNA game
- by Daniel Lopez
I am trying to create a simple 3D game but things aren't working out as they should. For instance, the mode will not display. I created a class that does the rendering so I think that is where the problem lies.
P.S I am using models from the MSDN website so I know the models are compatible with XNA.
Code:
class ModelRenderer
{
private float aspectratio;
private Model model;
private Vector3 camerapos;
private Vector3 modelpos;
private Matrix rotationy;
float radiansy = 0;
public ModelRenderer(Model m, float AspectRatio, Vector3 initial_pos, Vector3 initialcamerapos)
{
model = m;
if (model.Meshes.Count == 0)
{
throw new Exception("Invalid model because it contains zero meshes!");
}
modelpos = initial_pos;
camerapos = initialcamerapos;
aspectratio = AspectRatio;
return;
}
public Vector3 CameraPosition
{
set
{
camerapos = value;
}
get
{
return camerapos;
}
}
public Vector3 ModelPosition
{
set
{
modelpos = value;
}
get
{
return modelpos;
}
}
public void RotateY(float radians)
{
radiansy += radians;
rotationy = Matrix.CreateRotationY(radiansy);
}
public float AspectRatio
{
set
{
aspectratio = value;
}
get
{
return aspectratio;
}
}
public void Draw()
{
Matrix world = Matrix.CreateTranslation(modelpos) * rotationy;
Matrix view = Matrix.CreateLookAt(this.CameraPosition, this.ModelPosition, Vector3.Up);
Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), this.AspectRatio, 1.0f, 10000f);
model.Draw(world, view, projection);
}
}
If you need more code just make a comment.
