Some things on this page might wait until TPT++, because they're a bit messy to do in plain C, or would need a massive rewrite anyway
- Neut/phot flood fill
- Element specific functions for create, delete, HUD?
Gravity
- (probably not needed, now there is FFT grav) Force complete recalc after a certain number of difference only calculations?
- Only memcpy gravx+gravy if changed
- Only do bilinear_interpolation if changed
- Pointer swap for putting th_gravmap in th_ogravmap. Also, we don't need to memset th_gravmap - will get completely overwritten by memcpy in main thread
Small tasks
- Fix H2 reaction with DESL under high pressure
- Vertical flip?
- Make electrolysis of watr/sltw easier?
Medium tasks
- Precalculate single pixel steps for gravity (to make liquids in radial grav run faster)?
- Fix heat convection in liquids in radial gravity
- clipboard_pull_text
- Shared stamp clipboard
- Infinite stamps
- Order of elements in menus (configurable? also allow creating more menus with lua?)
- Update legacy_mode reactions (and make loads of things unmeltable in legacy mode)
- Fix off-by-one error in fillrect (need to check all boxes are still drawn with the right size/position after fixing)
- Random number generation - on Linux, rand calls random which locks a mutex and calls random_r. Only about half the cycles are spent actually generating the number.
- Bounds checking in update functions. All particles within 4px of the edge are killed, but update functions still check whether surrounding coordinates are within bounds.
Big tasks
- Rationalise number of properties used to describe state - currently have three
- Translations. Will probably involve unicode support and lots of new characters
- Configurable keyboard shortcuts (some work done on this already, not currently on github)
- Element property brush
Hard tasks
- Particle drawing order - e.g. stickman in water is sometimes hidden
- Fix edge direction detection (does not work at all angles, photons sometimes erroneously killed)
- Better fluid dynamics for liquids
- Thermodynamics in air
- Air vorticity
Stickman
- Draw head rotated in radial grav
- Temperature transfer between feet and head
- More homeostasis? Currently just warms up head
- Head currently behaves as a gas (walls)
Misc
- Stickman undo bug
