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.

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

I am using the first aforementioned entity called trigger_vphysics_motion for one room and i cannot get it to do quite exactly what I want. I am trying to create perfect weightlessness with also the ability to move freely, like deep space style

Trigger_VPhysics_motion mainly works just for physical objects. The player itself (and just he) uses trigger_graviy.

back again using trigger_vphysics_motion for another map, and Im using it to make a gravitygun, However in this instance I am trying to make the object grabbed to kinda just hover in front of the gun. For some reason it isn't working properly, inspite of checkboxes being set up and being parented to the gun, the effects remain super imposed to the region the physics originated.

What would you recommend I set up to do this hovering effect?

I would create a custom animation tbh and parent a model to it.

Or use a strong but small point_push.

I've already made a new gravity gun since the last upload of it, should I upload it for reference or for use?

Here, I updated the original download, it now contains all materials, models, sound, etc for it to work, and the new and improved gravity gun instance. It should be up in approx. 5 minutes.

Wow, yours has a LOT more entities and is a much more complicated. But definitely good referance material. I never considered using the teleport entities for this

EDIT, I tried out the trigger_teleport and i had 3 differant objects occupying the same point, violently twisting in place. At some point the weighted ball completely stopped and was all like
"NO, fuck this! I am not moving for nobody anymore! Imma float right here and not do nuthin no more!!"

What is also weird is that somehow I superimposed reverse magnetic feilds on wheatley, The other 2 wont even let him touch them anymore. He will phase right through them if i back them in a corner
