Gendoor
Gendoors, short for Generating Doors, are objects in the original Rayman game, Rayman Junior and Rayman Designer which trigger certain events. There are three types of gendoors available: normal gendoors, sparkling gendoors and Ting gendoors.
In Rayman and its spin-offs
Normal gendoor
Normal gendoors are the most commonly used ones and appear numerous times in the original Rayman game. In most versions of the game, most gendoors are invisible. Those that are visible are shown as sparkles. In the Game Boy Advance version and the DSi version, all gendoors are visible. They trigger an event when Rayman comes within range. In the original Rayman, they usually make cages or lives appear.
In Rayman Designer, there are several types of normal gendoors available. These are the super gendoor, gendoor size 1, gendoor size 2, gendoor size 3 and gendoor size 4. The super gendoor maintains its effect if the player dies, while the others reset. The size determines the range of the gendoor. Size 2's range is 50% larger than size 1, size 3's range is 100% larger than size 1, and size 4 has the same range as a Ting.
Sparkling gendoor
Sparkling gendoors act like normal gendoors, except that they need to be punched with Rayman's fist in order to be activated. A sparkling gendoor is always visible. These only appear in Rayman Designer and its spin-offs.
Ting gendoor
Ting gendoors are activated once all Tings of a specified colour, except the regular blue ones, have been collected. These only appear in Rayman Designer and its spin-offs.
Similar appearances in other games
Butterflies in Rayman Legends and Rayman Adventures act similarly to gendoors.
