1. Well, you don't have to be grounded to do the command. Up+HP+HK can be buffered, or you can do it in the air. I don't have any difficulty with this input, so maybe I'm missing something.
2. It's lenient by choice; the game is just looking for the 4 key directions of a 360° rotation. So Up-Back, Up, and Up-Foward all count as the Up portion of it. There are also alternate ways to do Jumbo's super.
1. You could do it in the air, but holding down a direction prevents you from doing the HP+HK movement in general, so for example, when holding down, you can't call an assist, hence the one frame problem.
2. Out of what I've seen, that's not really true? Previously I had to hit specifically U, F, D, B (or in any starting position) and not any of the diagonals until I changed the code to have that 8-way leniency (Using the $(direction) option). Similar situation with the half-circle into 3p, but that's more a personal issue since the game needs to detect the release of back first which isn't a problem for controllers ofc, but is for keyboard.
or maybe i have a skill issue lol
1. Alright, Texas Up +HP + HK can be done in air or by buffering, but I will increase the time players have for the command and allow it to cancel prejump animation.
2. Well, I thought I did, but I adjusted Jumbo to have the same leniency as other command grab inputs.
These will be in the next update.
