So I'm making an Android app/game using Unity where the user is able to "draw" by touching the screen. The drawings will be pixel art -- basically, a pixel art drawing function -- so everything should be pixel perfect.
Some functions I will add are:
- Changing brush size
- Changing brush color
- Filling areas
A game called Worldbox has a pretty similar function, where users are able to draw "land."
I thought about using the tilemap function of Unity, and even made a program that does all #1~#4 well. However, if the tilemap(drawing size) exceeds 100*100 tiles, the app took forever to load, and I concluded that tilemaps weren't suited for drawing programs.
A friend of mine said that I would have to make some kind of "editor" for this application, and Unity just isn't fit for that.
However, I only know how to make applications using Unity, so are there any Unity functions I can use to make this app?
The answer could be very simple(ex. Just use the tilemap function). It doesn't have to explain how I could make this app, but what I could use.
