how would i go about making an entity attract other entities? i can't find any documentation on the gmod wiki.
Use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/PhysObj/ApplyForceCenter]PhysObj:ApplyForceCenter[/url] towards your magnet entity. At the same time apply an opposite force of the same strength to your entity, because for every action, there is an equal and opposite reaction.

Otherwise you can calculate the direction of force towards the magnet as ( object_to_pull:GetPos() - magnet:GetPos() ):GetNormalized() * PullForceInUnits and use SetVelocity or ApplyForceCenter. The standard HL2 magnet works pretty good though for smaller tasks, I used it for a pulley/crane system for a helicopter.
alright, thanks for the help, i think this is what i was looking for.
