I built a door, using a few tutorials for the hingeconstraint, it connect the door with a part right above it. However, the door does not push well. How might I fix this?
Can you show where your hinge attachments are located, and a screen capture of the hinge properties please?
When you show the attachments, click on the attachment so we can see that they are facing the right way. But more importantly is the properties of the hinge constraint.
Your door might be colliding with the wall… try to make the wall noncollide to test this out… if its moving freely, then you need to give your door some room to swing open on the edge there.
