How do I simulate the gravgun?

models//props_junk/flare.mdl catches fire, lights the area, fires off effects and a sound when interacted by with the gravgun.

However, being able to simulate the gravgun might be useful. For making explosive barrels explosive etc.

The flare lighting is triggered by an input when it’s picked up by the Gravity Gun.

As for simulating punting, this should work:
local phys = ent:GetPhysObject()
if phys:IsValid() then
