With this function you can change the degrees of freedom of the movement of parts in Halocline Performance. The vertical direction and the two orthogonal horizontal directions are available.
This means, for example, that you can specify that an object does not move in the vertical direction, so that it cannot fall down or be lifted.
For example, if you have locked a part in the vertical direction of movement, you can no longer lift that object, but you can move it the same height above the ground.
If you move your hand upwards, the part will move under your hand (next point to the hand). If you let go of the object, it will continue to move with a constrained direction of motion.
Friction is physically calculated to occur only if the constraints on movement do not prevent it. Otherwise, a constant light friction is applied. Collisions take place.
Example: You have constrained a part in vertical direction. It will not rub with the ground, because it did not fall down and therefore does not create friction. Even if it is directly on the ground when you create it, there will be no friction with the ground because the object did not fall on the ground. You will rather feel it floating.
The restriction of the rotation of objects is automatically restricted in a way that makes sense to the movement restrictions. There are two cases:
If one axis is constrained, you can only rotate the part around that axis.
If two axes are constrained, you cannot rotate the object at all.
Tips & Tricks
- By constraining the vertical direction you can simulate a moving object.
- If you also constrain another axis, you can simulate the movement of a part on a conveyor belt or a drawer.
- A combination of several parts with movement constraints, e.g. a mobile trolley with a drawer, is not possible.
