How can you make a level box locked then unlocked?

Help! I can't solve this! can anyone add a screenshot of any Behaviors/Blocks Patterns/Codes I can use?

As in: Select level, complete level, and then unlock level.

Thank you!

Try searching the forums. This question gets asked a lot.

The basic idea is to have each level only unlocked when a condition has been met. This condition would have to be a Game Attribute.

THANKS! Not much but gives me an idea. BIG HELP, THANKS!

 


Thanks for the tip!
