how to use while?

[0920357689]

new smoke;
smoke = find_ent_by_class ( smoke, "toxicsmoke");
while(smoke != 0)
{
remove_entity(smoke);
smoke = find_ent_by_class ( smoke, "toxicsmoke");
}
use this will server dead

[infek]

new smoke;
smoke = find_ent_by_class ( smoke, "toxicsmoke");
while(smoke != 0)
{
remove_entity(smoke);
smoke = find_ent_by_class ( smoke, "toxicsmoke");
}
use this will server dead

what do you mean by "use this will server dead"

[Mxnn]

Statement while:
While condition is true, the loop will not stop.

[zwfgdlc]

new smoke = -1;
while((smoke = find_ent_by_class (smoke, "toxicsmoke"))
{
remove_entity(smoke);
}

[NiHiLaNTh]

new smoke = -1
while ( ( smoke = find_ent_by_class ( smoke, "toxicsmoke" ) ) > 0 )
{
remove_entity ( smoke )
}

Maybe he meant:

"Use this while server dead"

[0920357689]

Maybe he meant:

"Use this while server dead"
yes

my english very bad...sorry:cry:

this core is work

new smoke = -1
smoke = find_ent_by_class ( smoke, "toxicsmoke" )
while (smoke )
{
remove_entity ( smoke )
smoke = find_ent_by_class ( smoke, "toxicsmoke" )
}

@0920357689, you dont have to write this two times
smoke = find_ent_by_class ( smoke, "toxicsmoke" )

@0920357689, you dont have to write this two times
smoke = find_ent_by_class ( smoke, "toxicsmoke" )

In his case he must.

[YamiKaitou]

FYI, -1 is considered True

[JaGareN]

In his case he must.

Why?

If you are refering to me then I would assume that remove_entity(-1) would not be good. Hence why I said what I did :). But, maybe it wouldn't have a problem. IDK.

Edit: I just tried remove_entity(-1) and it didn't seem to complain.

[YamiKaitou]

Why?
Because he wants to remove all entities of that class

No, it was to anyone who was using while(smoke) since find_ent_by_class returns -1 and -1 is considered true.

Can someone explain this example with while condition?
The first post, and correct working looks like the same for me :(

[Bugsy]

It executes the code while the condition is met; repeatedly if the condition continues to be met. You can alter factors of the condition from within the code block.
while ( condition )
{
//do this code
}

Try
new smoke = -1;
while ( ( smoke = find_ent_by_class( smoke , "toxicsmoke" ) ) > 0 )
remove_entity( smoke )

[FiFiX]

while(find_ent_by_class (-1, "toxicsmoke"))
{
remove_entity(find_ent_by_class (-1, "toxicsmoke"));
}
But can someone explain me why that doesn't work? It seems to be "faster" and more optimal way..


TO BUGSY EXAMPLE:
And why in condition is -1? If entity haven't been fount, it returns 0, not -1 :/
So if
find ent != -1 (can be 0 - ent not found, and we are still deleting it...)

[hleV]

new Entity = -1;

while ((Entity = find_ent_by_class(Entity, "toxicsmoke")) > 0)
remove_entity(Entity);

[Bugsy]

Yes it should be 0, not -1. -1 is supposed to be specified if you do not wish to provide a starting entity.

If none is found, 0 is returned. If starting entity should not be specified, use -1.

LOL. If it doesn't work then it is neither faster or optimal is it?
