Function Vector_Clamp

engine/script/src/script_vmath.cpp:2556–2635

clamp input value in range [min, max] and return clamped value * * Clamp input value to be in range of [min, max]. In case if input value has vector3|vector4 type * return new vector3|vector4 with clamped value at every vector's element. * Min/max arguments can be vector3|vector4. In that case clamp excuted per every vector's element * * @name vmath.clamp * @para
