Do you think this will work for the racealias? but i need a cooldown and all that other stuff

If you are going to make a skill like this, it'll probably be easier for you to make as an ultimate and in block style. I only say block style because it makes life easier when you need to use a lot of if statements. If you really want to make it a say ability...I suggest inserting the code in the the wcs.txt under the event player_say block. I haven't been able to get the player_say ability to work in the race_db for whatever reason.

You also need to know if you want it to happen on spawn, attack or just aim and they turn.

Attacking: Should probably do a chance here. Just get the id and make it switch teams

Spawn: Use a if statement for team selection and then select a random person with a filter for the other team. Make that person witch teams.

Ultimate: Two options really here
 - Click: Make it to the same thing as the spawn one
 - Aim: Get the id of the player you are aiming at with the est_getviewplayer command. After getting the id make the same list of commands as the spawn or click ultimates

The getplayername command only gets the name...really only useful for doing a global command to tell everyone that this person used an ability on that person. Good Luck!
