Hey Zibuya,
To answer your question - yes it is possible.
Take a look at this map:
https://www.plazmaburst2.com/?s=9&a=&m= ... &id=980574It's not random player but it's a form of synchronized random number generator, something a random player generator will utilise.However, as what nightmar has mentioned, the main issue is with syncing of variables.
Random VAR trigger action is client sided and is different for every player.The general concept is
1. Ensure only one player executes the random trigger action. (region attached to moving door scanning the spawn area, deactivated after one use.)
2. Run sync trigger action to ensure that everyone obtains the same random variable.
3. Perform your corresponding tasks in regards to the random variable.
The example given above doesn't use this method, it uses URL trigger action to generate random numbers because the random number trigger action is flawed.I won't give you a detail explanation, because if you want to make mechanisms like these I expect you to have a great understand of variables as well as syncing in the first place.
Best regards,
Nyove
