I Believe this is because APROP_Friction was added only at 2.8.1 of ZDoom, and Zandronum 3.0 ZDoom base is 2.7.1 (i think ?)

Yes it is a property added in 2.8.1. It'll be in Zandronum after 3.0.

Looks like it wasn't added to Zan 3. I tried SetActorProperty(0, APROP_Friction, 2.0); in ENTER, but when I do Log(f:GetActorProperty(0, APROP_Friction)); it just says 0. TDRR confirmed that APROP_Friction is not supported in Zan 3.

Note, there appears to be a duplicate of this ticket at 0002713. Could someone check and mark as dupe, if so.

---

Here are two WAD files:
1. friction.wad - for APROP_Friction test
2. friction2.wad - for Friction actor property test

Command(s):
zandronum.exe -iwad DOOM2.WAD -file friction.wad +map MAP01
zandronum.exe -iwad DOOM2.WAD -file friction2.wad +map MAP01

Steps:
See console and/or terminal error.

It's up to Torr to determine if something gets ported out of sequence. I'll just mark this as backport later in the meantime.
