Hi there!

It indeed will not work. As stated on the help file, all platforms have these settings fixed, so they can work properly:

Creating Platforms
A platform is just a regular event with special effects.
There are three types of platforms: Normal, Fall, and Carry.
All Platform events have these settings, regardless of the event page settings:
- Through = true
- Frequency Speed = 5 (Highest)
- Priority type = below the player

By default, platform need to be on hole tiles, defined by region or terrain ids, so they can work. Changing their priority to be above player, and make the player walk below a platform, means that the player will walk on a hole tile, which also cannot happen.

Can you try explain to me why do you want that, so we can try to find a workaround?

Understood. You may be able to use my Character Manager plugin, and change the z index of the player or the rope dynamically when the player is about to pass below the rope.

But also, if the rope is above a tile that the player can pass, then, you don't need for that specifically rope event to be a platform. That rope event can be a regular event. If there is a tile below it, means that the player will never fall there. So you can also remove the region/terrain tag for that specific tile coordinate.
