Trying to change a mod tech icon to a HD version

[devilwarriors]

Hi,

I'm trying to change the icon of the nixie tube mod for a 128px wide version that I made from the building sprite, but it won't display right and I don't see what I'm doing wrong.

inside technology.lua I change the icon path to my file
icon = "__nixie-tubes__/graphics/technology/nixie-tube.png"

nixie-tube.png - 128px x 128px

But when I launch the game it look like that


Why?

You need to also set the icon_size property to 128 in your technology definition.

For example:

Code: Select all

data:extend({
 {
  type = "technology",
  name = "alert-systems",
  icon = "__Red Alerts__/graphics/AlertSystems.png",
  icon_size = 128,
  prerequisites = {"circuit-network"},
  effects =
  {
   {
    type = "unlock-recipe",
    recipe = "power-sensor"
   },
  },
  unit =
    {
      count = 40,
      ingredients =
      {
        {"science-pack-1", 1},
        {"science-pack-2", 1}
      },
      time = 15
    },
  order = "a-d-e",
 },
})

Nice, thanks for the fast answer!

You need to add this line aswell

Code: Select all

icon_size = 128(or whatever size your image has)

Default size for icon_size is 64.

EDIT: damn too slow

Oh that a pretty recent change, that explain why all mod have horribly pixelated icons right now (I'm new to the game).

Made two new icons from the one you posted. Feel free to use if you want although they might not fit with the style you are going for.
These two are 256x256 in size.

[devilwarriors]

Why 256? is the game accepting this size?

[keyboardhack]

Haven't tried it but i don't see why it shouldn't.
icon_size is an integer so i assume it can have any value.

[devilwarriors]

I feel like icons is one thing where I would prefer to control the render of the final size, since I know that this box is 128px wide on screen I prefer to make it that size rather than have the game resize it smaller. Photoshop probably have a better re-sizing algorithm than the game anyway if the max zoom quality is any indication.

Maybe it's because I come from web development where you couldn't trust IE6 to resize an image correctly.

I tried and yeah 256 work and look fine.
