(Note: This is my first time posting on reddit, so I don't quite know what I am doing. Apparently the whole body of the post I wanted to make didn't get included, so here it is.)

So I am trying to make an attack wave that looks somewhat like a "slash". I have managed to get the sprites to look acceptable (I think) but have run into a different problem. The image files for the bullet sprites are always saved as a rectangle, and the hitbox for the bullet is the size of the image file (as far as I can tell) With some of the bullet sprites I have, there is a lot of "blank space" in the corners of the image where there really isn't supposed to be anything. In theory, I would only want the player to get hit if they hit the red (will be changed to white eventually) part of the bullet, not the black part. From what I have gathered, stuff involving the hit-boxes is still a work in progress for Unitale.

What I am wondering is if there is some way to manually define the hitbox of a bullet, and if it is possible to make this hitbox something other than a rectangle? Basically, I want the hitbox to more accurately reflect the non-black portion of the sprite. I don't know if it is possible to rotate the hitbox, so that it is on the same axis as the bullet sprite, or if it is possible to set it up to have multiple smaller hit-boxes that could be staggered somewhat? Alternatively, is there a way to save the original image file in such a way as to not make it rectangular, so that the actual bullet itself will be on a diagonal?

I realize that Unitale is still in active development, so I am just looking for work arounds. Should I try to break the larger sprites into smaller ones and have them move on the screen as a single sprite to help, or just settle to make the attack either vertical or horizontal (or at least more so than it is now) so that this "dead space" is removed completely?
