Movement on the X an Z axis are combined?
- by Magicaxis
This is probably a stupid question, but I'm trying to simply move a 3D object up, down, left, and right (Not forward or backward).
The Y axis works fine, but when I increment the object's X position, the object moves BOTH right and backwards! when I decrement X, left and forwards!
setPosition(getPosition().X + 2/*times deltatime*/, getPosition().Y, getPosition().Z);
I was astonished that XNA doesnt have its own setPosition function, so I made a parent class for all objects with a setPosition and Draw function. Setposition simply edits a variable "mPosition" and passes it to the common draw function:
// Copy any parent transforms.
Matrix[] transforms = new Matrix[block.Bones.Count];
block.CopyAbsoluteBoneTransformsTo(transforms);
// Draw the model. A model can have multiple meshes, so loop.
foreach (ModelMesh mesh in block.Meshes)
{
// This is where the mesh orientation is set, as well
// as our camera and projection.
foreach (BasicEffect effect in mesh.Effects)
{
effect.EnableDefaultLighting();
effect.World = transforms[mesh.ParentBone.Index] *
Matrix.CreateRotationY(MathHelper.ToRadians(mOrientation.Y))
* Matrix.CreateTranslation(mPosition);
effect.View = game1.getView();
effect.Projection = game1.getProjection();
}
// Draw the mesh, using the effects set above.
mesh.Draw();
}
I tried to work it out by attempting to increment and decrement the Z axis, but nothing happens?! So using the X axis changes the objects x and z axis', but changing the Z does nothing. Great.
So how do I seperate the X and Z axis movement?
