I have a antifall command. Its fuction is to only Send the Player a Message but it also has a Variable and the Variable has the main function. When I do /antifall, it Send me the Message and the Varible performs its function but when I use return CMD_antifall( playerid ), it Sends me the message but the variable doesnt perform its function but the variable becomes 1 when it is 0 and 0 when it is 1. Why isnt it performing its function? Can anybody help!
