I haven’t used GD5 in some time but a feature I miss from other engines is the ability to enable a snapping grid when editing sprite points.
Makes it way easier to get quick, even points / collision hitbox points set up.
The way I imagine it is there’s a grid icon on the top of the edit points screen and you can change the grid size and enable / disable snapping when you press the icon and it creates a little modal window to edit it.
Maybe there’s a better way but that’d be nice.
