In maps? Use Hurt.

Gen_FX > Fire
or
effect "fire"

Depends how you want to use the fire.
In map, it's as user RisingXD said : you use env_hurt.

In script you can try

Code:
1
2
fire = {}
fire.a = {X*32+16,Y*32+16}

or something similar, doesn't really matter. Then you calculate distance between player and fire and if it's small enough, reduce the player's health.

P.S. is it even too small with amount set to maximum for fire effect ?

No, not a map... a script...

exactly i cannot set more amount because it's limited...
i would like to create a napalm MOD, but it's require enough fire... but currently its looks like impossible

Do you mean that the closer the person is to fire, the more damage he receives ?

--something simple like
dmg = 25 -- Max damage
dist = 15 -- current player distance
range = 200 -- Max range of triggering
print(dmg/(range/(range-dist)))

               local damage = 6 -math.ceil(Distance(player(id,"x"),player(id,"y"),firex,firey)/6)
               parse("sethealth "..id.." "..player(id,"health")-damage)
          end
     end
end


Where firex and firey are the positions of fire center. You can also use locals to shorten this but since I'm copy-pasting ...

P.S. You can change the damage calculation, it's entirely up to you. The hook can be changed too if you like.

I'm probably blind but I'm fairly sure that I've placed all ENDs ._.
The ')' error I've edited. The message box here doesn't really show the tabbing clearly so it's easy to miss little details when you don't see the overall view..

I mean thats why has no end because of ")"...
nobody said you are blind
now finally the last error is:

LUA ERROR: sys/lua/napalms.lua:24: attempt to perform arithmetic on local 'x2' (a nil value)

Did you replace "firex" and "firey" variables ? They're there just for example, you have to replace them with pixels of where the fire is supposed to work.

x2 is exactly where firex is. You need to replace it!

P.S. I said that I was blind myself ;P It's an expression.

@user VADemon: Are you sure..?
@user Marcell: You still don't define firex and firey anywhere.
That napalm call is a bit weird,why would you mix up all those arguments ?
One more thing. Your napalm is called upon say hook. You do not set a permanent/temporary source of fire. It's momentary. The effect appears for a short while (about a second) and disappears, that's the end of it. Why would you want to have continuous fire damage if your napalm is momentary ?
EDIT : The amount is weird too. The maximum is 100, yet you do "power * 10000"

I apologize in advance if this is totally wrong. I'm really unsure cause my brain can't think properly after reading books for school. I was doing exactly that before I wrote this.

I see you want to have explosions, add another argument for NewNapalm function and make the explosion there if you like...
