Does anyone know what helper is used for the switching blocks in blue emperor?

You can search the list of custom entities here. Perhaps jump block from xaphanhelper? You might have more luck asking in #map_making since the people there deal with this stuff more.

Jump block switches when you jump instead of dash, must be a modified version probably?

i think these are dzhake helper sequence blocks?

in the future tho #map_making might be better for these sort of questions yea + you can also always check for yourself by unzipping the mod and opening the map bin in lönn

Hmm, I'll see
