DDraceNetwork - mapping

Jeremy

Hey, anyone know if there is a perlin noise random map generator for DDNet maps

ReD made one some time ago https://discord.com/channels/252358080522747904/746534464984973323/815871303973470240

ReD

and than I lay this over an empty map. and I assign different blocks for different values of this gray, for example I say if the value is between 1 and 0.7 it's a unhookable tile, if it's between 0.6 and 0.7 it's a hookable tile etc

How do you relate the noise and entities? is there a set of rules you defined or how did you do this? (edited)

Or as you said, different hues on the grayscale, what did you use to do that?

for (int y = 0; y < layer.height; ++y) {
    for (int x = 0; x < layer.width; ++x) {
        auto value = perlin_noise.get(x, y, perlin_noise.frequency);

        if (value > 0.68) {
            layer.set_game_tile_at(x, y, entity_index_type::UNHOOK);
        }
        else if (value > 0.61) {
            layer.set_game_tile_at(x, y, entity_index_type::HOOKABLE);
        }
        else if (value > 0.52) {
            layer.set_game_tile_at(x, y, entity_index_type::FREEZE);
        }
        else {
            layer.set_game_tile_at(x, y, entity_index_type::NONE);
        }
    }
}

iirc the perlin noise params aren't defined there, so is this code reading an image?

What noise randomizer did you use for this

Like, for the image output (edited)

it's a perlin noise perlin_noise.get(x, y) gives you the value from 0-1 in this perlin noise before this code, i randomized the perlin noise

Okay, thanks!
