\doxysubsection{Detailed Description}
Constraints can be used to limit bodies movements, between bodies or between bodies and the world. Constraints can limit movement angle, translation, or work like a motor.

Constraints can be created with \mbox{\hyperlink{group__EPhysics__Constraint_ga49d1bce8073380c8e085caed3465d7e8}{ephysics\+\_\+constraint\+\_\+linked\+\_\+add()}} or \mbox{\hyperlink{group__EPhysics__Constraint_ga50ab20f0f16d79325b9d4377314d8777}{ephysics\+\_\+constraint\+\_\+add()}} and removed with \mbox{\hyperlink{group__EPhysics__Constraint_ga9108a722eb302109e47dd086a1db1fd4}{ephysics\+\_\+constraint\+\_\+del()}}. Can be applied between two bodies or between a body and the world.

The linear limits are defined from the body\textquotesingle{}s position on. The user will want to limit the movements on X, Y and Z axis where lower == upper axis will be locked, lower $>$ upper axis is free, lower $<$ upper axis is limited to the range.

The unit for every limits are defined on Evas coordinates.
