Help with randomizing bunker game

[Legobuilder]

Im making the roblox version of 60 seconds in gimkit. But i need help with ideas for randomized events in game… and how with picture examples do I make vents where as they shut you get slower and if all three get shut you are very slow (low oxygen) and you can check inside vents where robbers, raiders, and mutant bugs try to get inside…and you can even place traps to stop bugs…(this is surrvival game)

so in summary
bugs try to enter vent with three stages of getting close…if vent not shut after 3rd they get inside and attack…
raiders try to steal materials 3 stages like bugs
raiders attack wth 3 stages of entry attempting like bugs
you must shut vents to keep em out
too many vents shut you get slow from low oxygen
…I never got to finish this and i need help still…since me and wolftechs collab did not work out… @Lostsea3 and @Sythic pls help as well

I’m sorry I don’t fully understand this games mechanics, so I can’t really help. Since it’s based off of a Roblox game, could you tell people the name of that game so they could search it up and play it to figure out what you’re trying to make? I don’t have Roblox so I won’t be much help here. I do feel like the problem was well explained, but I’m a visual learner so I can’t really understand this. Hopefully someone can help you though.
