En Yi 259fa114ca Fix water filling rate 2024-08-13 18:17:52 +08:00
En Yi 0a6e7b4ddc Add delta time handling 
Internal Changelog:
- Major change: all engine that does counting uses delta time instead of
  frame counting
- Animation runs at 24 FPS
- Water fill is at a constant rate as well
- Particle update will need to be given delta time as well.
- Particle system is not updated to use float, so no delta time handling
  for the system in this commit

En Yi a2c061c5e8 Place position field into Entity 
Position is so commonly used that placing it into Entity from the
CTransform components reduces the reference to CTransform.

Void Particle proved that it made development much easier.

En Yi 2968172921 Use signed int for water runners 2023-11-11 12:06:19 +08:00
En Yi 963ba34164 Make water runner travel faster 
Changelog:
- introduce travel speed: how many move can the water runner make
    - normal movement cost : 2
    - water movement cost : 1

En Yi 0c52718695 Update water flow rendering logic 2023-07-26 23:16:50 +08:00
En Yi 2e368704ce Fix water runner interaction 
- Add null check for bbox for moveable check
- Null after free when freeing runner

En Yi f6c5fa10fd Add simple water flowing visual 2023-07-24 23:59:19 +08:00
En Yi 478dea2d9c Add air pocket tile 
Air pockets are just tiles with a max water level lower than the
absolute maximum

Also, make air pockets not reachable by water runners
 2023-07-24 22:15:13 +08:00
En Yi 7d00d348f6 Put max water level into each tile 
This is to create air pockets
 2023-07-24 21:58:50 +08:00
En Yi 0a76826c27 Modify player collision with water blocks 
Collision now handles different water level
 2023-07-24 21:19:16 +08:00
En Yi 62c74fe545 Add water levels proper 2023-07-22 21:09:12 +08:00
En Yi eed785162e Update scanline fill function 
Changelog:
- Fill only a range of reachable tiles instead
- Tweak fill complete check
    - Count tiles filled, if zero: complete
- Allow multiple runner to fill without breaking the game
 2023-07-22 20:29:20 +08:00
En Yi cf807be7a2 Remove unnecessary state 2023-07-22 20:07:05 +08:00
En Yi 6097ec6e0d Complete basic water flow algorithm 
Changelog:
- Add in scanline filling process
- Use signed integer for calculation
- Generalise BFS to only depend on the current cell
    - During the search for the lowest reachable tile, allow a single
      tile equal or higher to the starting tile
      This is to allow moving upwards when no valid lower tile exists
 2023-07-22 15:52:55 +08:00
En Yi 89d962d2bc Fix runner bug of not reaching water surface 
Also fix bound checking in runner
 2023-07-21 21:19:38 +08:00
En Yi 6e2ccfa875 Improve reachability search for scanline filling 
Just do a second BFS from the current position, reset the current
scanline reachability.
 2023-07-20 23:25:32 +08:00
En Yi 7607827420 Split out state for resetting and starting BFS 2023-07-20 22:58:09 +08:00
En Yi 34655d5c0a Visualine reachable scanline 
Also tweak logic for lowest point
 2023-07-20 22:51:15 +08:00
En Yi dc20a6b992 Fix lowest point check and movement delay 
- This allows separte movement delay for each runner
- Lowest point has to be not in water
 2023-07-20 22:25:57 +08:00
En Yi a080b5ee0a Add water checks in BFS 
Also refactor the BFS logic to generalise the next tiles to go
after the tile checks
 2023-07-20 21:23:43 +08:00
En Yi 7af75b8366 Implement runner movement to lowest position 
Changelog:
- Add new state for when runner reaches target position
- Skip movement if already on target position
- Add extra handling for spawning on solid tile
- Fix tile toggling bug on the same tile
 2023-07-19 23:32:53 +08:00
En Yi a0f6cf3471 Visualise path from BFS + Improving BFS 
Changelog:
- Avoid continuous BFS by changing state after BFS completion
- Reset to BFS state on tile change
 2023-07-19 22:44:49 +08:00
En Yi 5b3cbd1bba Implement BFS into water runner 2023-07-19 19:16:35 +08:00
En Yi b52b662da9 Add water runner entity into game loop 
Changelog:
- water runner needs ctransform + ctilecoord at least to be in the tile
  update system
    - Update the tilemap update system as well
- Update rendering function for water runner
- Update water runner creation to handle failure to create
- Add a tag for water runner (pending proper tag)
 2023-07-19 11:15:34 +08:00
En Yi ebffd48958 Ready a water filler/runner entity 
Changelog:
- Add new component: water runner component
    - specific for such an entity. Not general, but i dont really care
- Implement adding and freeing the water filler entity
    - Component involves dynamic memory allocation, so need custom
      function to add and free
    - May look into custom allocation for this part in the future.
