How to make smoke (for i.e. from smoke grenade or from campfire)?

Question

How to make smoke in Godot? And how to make player invisible for enemies if he hidden from them by smoke?

Answer 1

You can use Particles for the smoke.
You can increase the number of particles to hide the player but if a Ray trace the player they are not really hidden. You can make them really hidden by set_visible(false) in the code too.

Can you give some example?

You can make them really hidden by set_visible(false)

In third person shooter it will be ugly solution.

I can use some 'hidden' property but how to detect moment when to set/unset it?

Regarding the moment of when to set it, take note how much time until the smoke covers the player before setting the set_visible to false. This will prevent the sudden invisibility of the player.

In terms of third person shooter, I don't have much experience with it. You can look for Shaders to accomplish it, I think.

I need some very basic example.
