War of Dungeons

worked on chunk loading and rendering

fixed screen scaling

linked the rendering API so I can Issue sprite draw calls from the main loop

Got a GPU based sprite batcher to work. currently it is only a debug window

played around with the water shader

• added specular highlights as part of the shader
• layered some more sine waves to achieve a more natural look

added a water shader, I achieved this by stacking 20 sine waves in the fragment shader, this achieved a nice moving texture when I itterated over the sine waves using a time variable,
next I will try to create a new rendering API that can handle the old renderer and the new shaders

made a shader that modulate alpha of a triangle, I will use this to modulate the brightness of water

get shaders to work

fixed a bug with biome blending where tiles arranged in the order:
#@
@#
where @ and # represent individual tile types
would create a weird visual artifact, I managed to fix this with a if statement

worked on player movement

• added a delta time in an equation where it was missing
• organised the code
• fixed screen scroll issue where the screen jumped around a bit

what I did

• Moved the rendering code onto a separate thread
• Cleaned up the code
• Separated the code into separate functions

now the game is running on 3 threads in total:
1: chunk generation
2: player movement and miscellaneous
3: rendering

devlog to account for the time I lost by having a incorrect folder name. in the time I worked on the incorrect project folder I worked on the tile and biome generation, I also optimised a bit

added a beach biome by creating a new threshold and comparing it to the terrain heigh. This ccaused many rendering issues however I was able to resolve them

added a game icon and debugged a bit. also I renamed the project to be different than the project I reused the code from.

fixed biome blending (it wasn’t working because some tiles were rendered over the curved bits.) I had to rewrite the code to render the curved bits last

tried debugging biome blending. I tried everything to get this to work added debug statements and rewrote some code multiple times however I was not able to find the issue so far

worked on biome blending. I made 4 textures for each corner that the tile can be in. I put this texture inside the originall tileset and added some code to check which tiles are nieghbouring

tried fixing biome transitions. In this attempt to get biome blending to work, I separated the darker bits from around the texture and the inside. I wanted to render the “mask” only near water, however, this approach is hard to get to work and is inefficient because of the ammount of needed textures

added new tile types using libresprite (free version of asprite) and optimised rendering by not renderigng empty tiles like the ocean

got auto-tilling to work. I used the 15 piece tileset as presented in this video: https://www.youtube.com/watch?v=jEWFSv3ivTg&t=77s. I implemented by adding an array to decide where to clip the texture based on the neighbouring tiles

added a function to work out player spawn position to be on a piece of land in a deterministic way I did this by adding a random value to the X and Y position until the player was on a full tile

worked on player movement and terrain generation. Also added a predictable random number function to get player spawn position. The function uses the seed that the terrain generation uses

added even more biomes

work on more biome generation (stacked multiple perlin noise textures to create values for variables like temperature and humidity. these are used to generate different biome types

added multithreading (separe threads for chunk generation and everything else) and I added some new biome types

worked on player movement

started working on biome generation

worked on new cave type’s (spagetti and swiss cheese) made a unoptimised function for generating them. Need to do some multithreading

debugged the chunk loading and unloading (moved the chunk code away from the rendering loop)

added automatic chunk loading when player moves

made a function that works out the first and last chunk’s coordinates that should be on the screen, I will use this to generate chunks that are on the screen

got ofscreen chunks to unload, next step get ones on the screen to load

added the player sprite, also managed to split up the world into chunks. currently working on loading and unloading the chunks.

added the perlin noise tiles to the SDL window

visualised perlin noise output for testing

get perlin noise output to work

work on chunk generation using perlin noise

initialise repo by repurposing some code from an old platformer
