is it possible to make a block transparent?

you can just give it no sprite and you won’t be able to see it just go into the sprite editor and press the X

@seamothmaster45 That’ll make it completely invisible, and an empty sprite also has no collider.

If you want to make an object transparent you can use the alpha behavior. It uses percentages so if you input 50 for example, the object will be half transparent. If you input 0, the object will be completely invisible but it’ll still be able to touch other objects, unless you turned collisions off.

You can do something like this:
Once --> Number (50) --> Alpha

Which will make the object 50% transparent as soon as the game starts.
