Nope. I haven't changed anything from the install of last night. I will just start a new project. I'll create a tiled background for the first layer, then lock it like in the tutorial. I start a new layer on top of it. On this layer, I have two objects: One solid, one 8Direction. They do not collide or stop.
The two sprite objects both have this second layer as the layer under it's properties in 'Common'. Depending on changing the Z Order, the moving object will pass over or under the solid object but won't stop.
The only events I have for the moving object are Every tick set angle towards mouse, and move forward when left button is down. The behavior I have for the moving object is 8Direction. The behavior for the solid object is Solid. That's all I have.
