allways in plugins you need to add:
#includes, #defines are optional but #include is allways needed.
EXAMPLE: If you were making a plugin about TFC Weapon you would:
PHP Code:
#include <amxmodx>
#include <amxmisc>
#include <tfcx>
<--
might need to be added depending on what you add to your plugin. PM me if you need some help on things ;)
