[2.2.12 Pre1] Continuous Plane Mover oddity?
This also happens in 2.2.11 but since the prerelease exists... I did a test in there just in case. Anyways...
This was done in UDMF.
53 - Continuous Plane Mover (Slowdown) Icon is a segmented Yellow Arrow For some reason when you jump from these type of moving planes, your jump abilities will not work as some flags aren't set... but a closer look shows that you can get stuck briefly on the plane and then you'll get launched in the air. The timestamps when getting stuck briefly happens at 19 & 26 seconds.
56 - Continuous Plane Mover (Constant) Icon is a White Arrow Seems to work fine but looking a bit closely you remain in your jump frame if you were moving 'upwards' but the moment you start moving 'downwards', you'll land, even though you're being pushed upwards by the moving plane. You also move slowly during this until you're off the moving floor plane. The slowdown bit happens at around the 54 second mark of the video.
EDIT
Forgot the post the test map. Oops. This replaces MAP01 and was made in UDMF.
