Create exported enum variable with UI like CollisionLayer

[gertkeno]

You (might) want @export_flags

Though, collision layer and mask use this because it can set multiple layers or masks on/off. If you only want one style set at a time, you should stick to enums.

This is implemented as a “bitset”, binary being used to store up to 32 true or false values. When using the @export_flags you will get an int instead of an enum, checking values involves binary operations like this to check one value my_flag & 0b1000 != 0

I wrote a similar example as a advanced recommendation to replace an Array[bool] type.

Extreme Noob Question Arrays/Looping

If you want to go really effecient, you can notice that an array of bool is the same as a binary number 1001 vs true, false, false, true bitwise operators let you use ints as bool arrays, and so does @export_flags. this lets you create properties in the inspector like collision layer/mask where you can select multiple true/false values. @export_flags("Fire", "Water", "Earth", "Wind") var spell_elements = 0 func has_water() -> bool: # binary is flipped compared to the flag names retur…
