<function name="SetDamageForce" parent="CTakeDamageInfo" type="classfunc"> <description> Sets the directional force of the damage. <note> This function seems to have no effect on player knockback. To disable knockback entirely, see [EFL_NO_DAMAGE_FORCES](https://wiki.facepunch.com/gmod/Enums/EFL#EFL_NO_DAMAGE_FORCES) or use workaround example below. This function only affects entities using the VPHYSICS movetype. This means players and most NPCs won't receive the force vector you provide as knockback. ⤶ If the entity taking damage is using the WALK or STEP holdtypes, the damage force is instead automatically calculated. It will push the entity away from the inflictor's <page>Entity:WorldSpaceCenter</page>, scaling the push by a calculated value involving the total amount of damage and the size of the entity.
