So I'm creating a mod where i want to add a research to the tech tree, but when i do the box where the sprite is supposed to be just remains empty. I've tried both the resolution that the normal games sprites are in and the one the tutorial on the wiki is in, but neither work.

In game it looks like this:

The code in the prototype file like this:

Code: Select all

data:extend({
    {
        type = "technology",
        name = "shuttleTrain_tech",
        icon = "__ShuttleTrain__/graphics/icon_shuttleTrain_tech.png",
        effects = 
        {
            {
                type = "unlock-recipe",
                recipe = "shuttleTrain"
            }
        },    
        prerequisites = {"automated-rail-transportation"},
        unit =
        {
          count = 70,
          ingredients =
          {
            {"science-pack-1", 2},
            {"science-pack-2", 1},
          },
          time = 20
        }
    },
})

If you need more information the repository for the mod is here or you can just ask

Hope any of you can help me with this seemingly easy problem.

Have you tried 32x32 icons?
Unless specified otherwise game draws those pixels. All vanilla techs now have

Code: Select all

icon_size = 128,

to declare their hi-res quality.

Thank you so much that was what was needed. I knew the answer would be simple
