Thanks to @makavel for testing and helping and thanks to @Nukem for telling how to fix the bugs.

Why did you set it to 11 and not to 1 or 0?

Why did you set it to 11 and not to 1 or 0?

If you set it to 0 you are immune to weapons too. If you set it 0 < x < 10 hitboxes are weird. Not sure what causes that, but I tried the highest possible value where you can not knife and 11 should be ok.

So what dvar is that?

So what dvar is that?

player_MeleeRange obviously.

[Pozzuh]

How would setting that to 0 make all players invincible? That didn't happen in any cod.

As you can see it's a float address and of course other dvars are also using that float dvar.

Well he`s right. It changes some others dvar value also so that effect to other dvar`s aswell which are also associated with the same float value.
