Molotov, burning props, spreading fire?

[Dugehong]

Herro.

I was wondering how hard it'd be to create something along the lines of a molotov (or just a grenade) that explodes on impact (with anything) and bursts into flames,
slowly spreading across the area it landed, igniting the floor so that players take damage from running over it along with putting props on fire - eventually
making them disappear.

I know it's a request, but feel free to PM me if you'd like to walk me through it and explain so I learn something during the process, would rather prefer that
instead of being spoonfed - but if you really cannot be arsed to, don't bother.

Thank you!

Did you check garrysmod.org first? If you want to learn how to create something like that yourself, take one off of garrysmod.org and examine its code. You should be able to get something started from there.

Thank you for your answer.

Unfortunately, I have already checked garrysmod.org, but none of the molotov models there contain
the code for spread or ignition.

If you could possibly redirect me to another item on garrysmod.org with the functions above, I'd be most pleased, but only if you'd bother.

Thank you again!
