Ah yes Indeed! I also make some slight changes. I made an extra "On key A pressed" underneath the original.
for the original I made a if "maskplayer" is "jumping or falling" toggle "start ignoring user input".
On the new :On key A pressed" if "maksplayer" is on the ground "start ignoring user input".
Therefore, when player is in the air he won't fall straight down. But gives him a bit momentum in the air, amusing you are hold the left or right keys. On the ground he is not mobile while attacking even when holding left or right during attacking.
This is what originally aiming for.
Again, Thank you sooooooooo much for the .cap edit and sharing your knowledge of Construct!
