Server crashes if you call a deleted sprite/textdraw

[sseebbyy]

I removed a sprite, then I tried to call it back, but the server stopped.
Shouldn't this be avoided ? To not crash the server if the sprite/textdraw doesn't exist...

The question is: Why would you call a deleted textdraw/sprite ?

I just tested it, but there are other cases...
You can forget that you deleted the sprite/textdraw, and just call it.

Anyway, Gudio gave me some answers:

<Gudio> its because when you do remove or delete
<Gudio> instance in squirrel lang still exists
<Gudio> but not in cpp
<Seby> ah :/
<Gudio> when you call it again after removing, cpp doesnt know what do to
<Seby> why you just don't set it = null; ?
<Gudio> it needs some error handlers or some hack to set variables automatically to null when instance is the same

You should set null for variables that you remove to avoid crashes in the future.
Example:

Code: [Select]

if ( Timer )
{
Timer.Delete();
Timer = null;
}
