Slider constraint allows the body to rotate around one axis and translate along this axis.

Icon Size:
Defines size of the icon in the viewport.

Icon Width:
Defines width of the icon in the viewport.

Master Object:
Master object is base object of constraint. You can pick Dynamic / Static / Kinetic object for this. If you don’t use this option, objects constraint to this icon position.

Disable Collision:
When checked, disable collision between master object and constraint object.

Constraint Object:
You have to pick Dynamic Object for this.

Pick:
Select single object to add from viewport.

Add:
Select multiple objects to add from scene explorer.

Remove:
Remove selected objects from the list.

Softness:
Defines the softness of the slide distance.

Bias:
Defines the tolerance for a correctional force to counteract an error in the simulation when the limits are reached.

Relaxation:
Defines the amount of bounciness when the limit is reached.

Distance Limit:
When checked, slide distance limits are enabled.

Low:
Defines the lower slide distance limit.

High:
Defines the higher slide distance limit.

Softness:
Defines bounciness or springiness of the slide distance limit.

Damping:
Defines dampening force for the slide distance limit.

Restitution:
Defines restitution value at the slide distance limit.

Linear Motor:
When checked, the linear motor effect is enabled. A motor is applied constant force to the object.

Velocity:
Defines the force along the sliding axis.

Max Impulse:
Defines the maximum allowed impulse.

Breakable:
When checked, constraint breaks when objects get some impulse.

Impulse:
Defines breakable impulse threshold. If object get impulse larger than this, constraint breaks.

Rolling:
Softness:

Defines the softness of the rolling.

Bias:
Defines the tolerance for a correctional force to counteract an error in the simulation when the limits are reached.

Relaxation:
Defines the amount of bounciness when the limit is reached.

Angle Limit:
When checked, angular limits are enabled.

Low:
Defines the lower angular limit.

High:
Defines the higher angular limit.

Softness:
Defines bounciness or springiness of the angular limit.

Damping:
Defines dampening force for the angular limit.

Restitution:
Defines restitution value at the angular limit.

Angle Motor:
When checked, the angular motor effect is enabled. A motor is applied constant force to the object.

Velocity:
Defines the force along the limit axis.

Max Impulse:
Defines the maximum allowed impulse.
