Override background

[Lobby]

Hi, as proposed here it's now possible to change the color of the background. The background basically persists out of a tile frame that's drawn over and over again. Unfortunately it's a bit less simple, as there are some special cases due to elevated coast lines. As a result you have to provide 3 frames to override the background:

Frames b and c are used to draw the background above water at the edges. This is crucial as ocean is drawn everywhere and has to be overdrawn at the correct positions.

Starting with game version 1.11.08 you should also provide a fourth frame that will be used for more optimized drawing:

It should represent a 4x4 tile grid of frame a.

The original frames look like:

This sample replaces the background with a black one:

For your own background, just recolor these images

The code to override the background looks like:

Code: Select all

[
  {
    "override":true,
    "id":"$anim_blank00",
    "type":"animation",
    "frames":[
      {"bmp":"frames.png","w":32,"h":16,"handle y":8},
      {"bmp":"frames.png","x":32,"w":16,"h":16,"handle y":8},
      {"bmp":"frames.png","x":48,"w":16,"h":16,"handle x":-16,"handle y":8},
      {"bmp":"frames_tiled.png","handle y":32}
    ]
  }
]

As you are responsible for setting the frame handles properly I recommend to just reuse this code instead of writing it on your own.

@Lobby I really like the brown background in the first image you posted in this topic. Could you post that as well?

Thank you in advance!

The first post was updated to reflect new functionality in 1.11.08. Your background should basically provide a 4x4 tiled frame as well for the game to use to draw big chunks of the background at once. This reduces draw calls significantly if a lot of background is visible on the screen.
