Hi,
You can add boolean var to Jugador (Asreload= true (default))
condition: on mouse leftclick AND Jugador Asreload=true
action : set Jugador boolean var = false
Jugador spawn bullet
wait "reloadtime" (variable,1sec,10sec what you want...)
set jugador bolean var= true
well done
EDIT: you can change condition "on left click" by "on left mouse down"
