Here are two errors:

Код:

if(newkeys == KEY_WALK)

Firstly, you are checking for newkeys with &, not with ==.

And at the other hand, I dont think there is a key like "KEY_WALK" - go to wiki.sa-mp.com, search for "GetPlayerKeys" and grab the key definition of your desired key.

Corrected version, using the Mouse LMB for the engine:

Код:

if(newkeys & KEY_FIRE)
