Tomik18 Ok, if I understand correctly, to change an entity their are several ways.
1- open it's .fpe file and change the line "defaultstatic = x" 1 for static/0 for dynamic
2- right click entity in editor and change setting "Is Static" to "No"
3- while selecting entity in editor tap the "Y" key, it will glow "Red" for static/ "Green" for dynamic.
Now as for the "floor" piece to support the player, you will need to add "colon" to it's script.
I have never used it that way, so not even sure if it will work?
My games never have bugs. They just develop random features..
Lots and lots of random features...
