Hi !! Just a few suggestions- I’d love to see these new actions get added.
‘SetRandomColor’ for lights. Randomly picks a color when used. Useful for parties, disco, nightclubs, dance floors, etc
“OnHold” for Basic Shape Button. Holding the interact key repeatedly play actions over and over- Great for mini games with spitting fire or spraying water at moving enemies; a turret; tower defense games, fireworks, science museum, etc.
“OnPressure” for Basic Shape Button. Activates whenever someone stands on button, leans against it on wall, or hit on ceiling with a jump. Could also activate with hitting using a physic item throw. Useful for creating traps with having a button on floor hidden in grass; basically like pressure plates from Minecraft!!
Or we could just have actual pressure plates; both sounds good to me. 
“OnWeaponHit” for anything; starting with Basic Shape Button; allows you to choose a specific weapon that can be hit to activate. Very useful for carnival games like throwing pies/balls and hitting bottles/targets with. Maybe archery stuff. Shooting gallery game and so on. Can be used to play sounds, explosions, increasing score, or forces itself to hide after being hit and so on!
