Okay so I know this has been around for 1 year and more but I found a really simple way to do this. You get the player coordinates, property and game overlay devices and make the property measure your Y Position by making the player coordinates device update that property with your y.
THEN, you make it so every time your position changes (on player coordinates device) it sends a broadcast. The game overlay device should have a block in it that runs every time that broadcast is sent.
In the block, all you have to do is:
set text:
create text with:
"Height: "
get property : "[Y POSITION PROPERTY]
Since you fixed it, why don’t you make your own guide! This guide has no pictures, and it could be helpful to some people who need pictures and/or a different explanation.
Another quick note: please don’t reply to old conversations – like, say, if two people had a discussions a year ago, don’t add onto it! You can still bump Community Made Guides and some Art & Devices topic, but don’t add onto old conversations.
