PICO-8 Text Editor with Effects, #3

Today I made a bunch of changes to the text editor. I added a movable cursor, re-added particle effects, and changed the method of drawing text.

• Particle effects: I used the idea of saving each letter’s screen position at draw time and creating the particles afterward.
• Cursor: This was pretty straight forward; I just changed all my add and delete operations to use the cursor position.
• New method of drawing text: instead of looping through each screen position, I loop through the letters. This makes handling line breaks much easier.

The hardest part was particle effects for deleted letters. The problem is, once the letter is deleted, where do I draw the particles?
I don’t reliably know the letter’s screen position until it’s drawn, but deleted letters aren’t drawn. What I ended up doing is referencing the letter left of the deleted letter, although this solution has its own problems.
