Gravity manipulation
I am working on a concept for a custom map and I want to try utilizing gravity tools to create some sort of magnetic force gravitational pull. However I have no idea where to begin on that. Tips?
Fracture: there are some great entities out there that can change the gravity of objects within its' field.
Someone without prior knowledge can use a trigger_gravity - however this entity is not as smooth as some people can hope.
I would use a trigger_vphysics_motion. This entity affects the player and objects smoothly. You can see a demo of this entity within my 'Chicken's Derp' map. The trigger is towards the left of the player when you spawn.
In order to create a pull on objects - you could use a trigger_push or a point_push entity set to minus push.
for some reason it wont download from the PTI to my game. Nothing is showing up in my queue.
I tried testing with the entity anyway. I can't seem to get it to make it pull entities to its center
Actually, the simplest thing to do use a trigger_push brush set to push toward the thing or place you want objects to go. You can't put a negative value in a trigger_push or a point_push entity as far as I know. Besides, that is not really what you want.
Try a point push, and whatever force is, change it to a negative.
Aperture Science: We do our science asbestos we can!
Let me repeat myself, I don't think you can do that.
A point_push with a negative Magnitude pulls objects to it, and it works the same for a trigger_push. It pulls objects instead of pushing it.
I was actually experimenting with that as well, but i think i set the numbers too high. Cubes kept firing off like bullets. 
I will try messing around with them some more
