Hi there!
For this to work, you will need to use 3 of my plugins:
- Character Frames - PAID
- Character Poses - PAID
- Diagonal Character - FREE
- The Character Frames, requires you to have all frames on the same image file.
- The Diagonal Character, also requires you to have all directions on the same image file.
- The character poses, you can have separated files for Idle, Walk, Dash, and Jump.
They are all compatible with each other. Make sure to read the help file of all of them, listed on their itch io page, so it fits the format you want(not so sure if I understood you correctly and also give the proper answer)
Don't know if it is compatible with DotMovementSystem. Probably not =/
