Well, I'm not sure which maker you are using this for, but in most of them you can set up a conditional branch that looks like this.
CODE
@conditional branch=switch 1 is on
switch 2 = on
else
switch 2 = off
switch 3 = off
change player hp - 50
flash screen
basically what it's doing is checking if the needed switches are on, if they are not it turns off all switches, and I also slipped some hp damage to the player for getting it wrong. For more than one switch being on you simply set it up like this.
CODE
@conditional branch = switch 1 is on
@conditional branch = switch 2 is on
switch 3 = on
else
switch 3 = off
switch 1 = off
else
switch 3 = off
switch 1 = off
end branch
end branch
Sorry if that one was a little confusing, but basically what it does is check if switch 1 is on, if it is then it immediately checks if switch 2 is on. If switch one is off it goes to the first else, if switch one is on but switch 2 is off it goes to the second else, if both are on it goes to the first section and turns on switch 3. You can just repeat this for as many switches as needed.
I hope this made sense, if you are still struggling or confused, I'll make the event for you and post a screen shot, just let me know.
