gravity gun

what enables things to be picked up with the gravity gun? ALso, hwo do I put the super grav gun in maps?

To enable things to be picked up by the grav gun, make a prop_physics entity and select the model for it from the many that there are. Then, for flags, mark "Enable pick-up on phys gun grab" or something along those lines. I think that should enable it to be picked up.

As for the the super grav gun, well, that has been answered many times, and can easily be searched. You are only supposed to have one question per topic anyhow, I believe.

I looked and there were a bunch of different answers so I dont know which to use, which one should I use?

Ok, as I said, make what you want to be picked up a prop_physics, and if you dont change any of the flags, that will enable it to be picked up and shot around like normal. The rest of the flags are pretty much self explanatory (Like 'Motion Disabled', 'Enable pickup on Physcannon grab', and etc.)

So if you leave the flags default, you can pick it up. If you need it to act a certain way, mark the flags accordingly.

that wasnt what I meant. I meant I've looked at all the topics for the super grav gun adn there are many different ways to implement it into ur map, which way is best or actually works?

You should have said that before, as I thought you were talking about how to pick things up with the grav gun, which I am sure is why only 1 question per topic is allowed.

As for which way to do it, experiment. I am sure it would take less time than waiting for an answer. I havent done it yet, so I cant say how.

If this is for HLDM2 then you will need to use prop_physics_multiplayer. Once you placed it in your map hit ALT + Enter to bring up the entity's properties. Click on World Model then on the Browse button. Select a model from the model browser by double clicking on it. For example props_c17\oildrum001. Now click on the Flags tab. Check the Enable motion on Physcannon grab checkbox. Click Apply. Make sure your newly placed oildrum is where you want it.

Use what they said prop_physics or func_phyicsbox to enable the pick-up
of the item, anything will work, it is all dependent on the weight of
the object, if it is relitively light then you will be able to pick it
up automatically, but if it is too heavy you will only be able to push
it with the grav gun. If your object is too heavy, try making the mass
scale a number less than 1 like ".50".

As for the super grav gun I dont think you can put it in a multiplayer
map if that is your intention, plus it would make for crappy gameplay
if the super grav gun was in it (it would be way too easy to kill
people)

If you mean brush-based objects rather than models you want to use a func_physbox.
