Can someone help me to code a Procedural Terrain Generation from Tables?
Can you show the example of source information and how the result must looking for?

So you have an empty table named terrain. There are variables g and a. a has air.png, and g has ground.png. then it will put the variables in the tables like this: terrain = {a,a,a,a
g,g,g,a
g,a,a,g
g,g,g,g} when it will generate the table it will somehow draw the terrain.
g,g,g,a
g,a,a,g
g,g,g,g} when it will generate the table it will somehow draw the terrain.

Also it won't be the same terrain, it will generate not the same.

The simplest way to do it is (not tested):KedyZ wrote: ↑Sun Sep 25, 2022 2:26 pm So you have an empty table named terrain. There are variables g and a. a has air.png, and g has ground.png. then it will put the variables in the tables like this: terrain = {a,a,a,a

Code: Select all
tileSize = 32 -- for image 32x32 pixels
a = {image = love.graphics.newImage("air.png")} -- image 32x32 pixels
g = {image = love.graphics.newImage("ground.png")} -- image 32x32 pixels
map = {
{a,a,a,a},
{g,g,a,g},
{g,a,a,g},
{g,g,g,g},
}Code: Select all
function love.draw()
for y, xs in ipairs (map) do
for x, tile in ipairs (xs) do
love.graphics.draw(tile.image, (x-1)*tileSize, (y-1)*tileSize)
end
end
endhttps://love2d.org/wiki/love.math.noise
Code: Select all
local w, h = 4, 4
map = {}
for y = 1, h do
map[y] = {}
for x = 1, w do
local value = love.math.noise( x*10, y*10 ) -- x10 makes more thick randomness
if value > 0.8 then -- 80% air and 20% ground
map[y][x] = g -- ground
else
map[y][x] = a -- air
end
end

nevermind but it shows the same every time and if i want to put it in function.load it shows me that i need to put an end at line 1

Don't forget to define a and g.

function love.load()
tileSize = 32 -- for image 32x32 pixels
a = {image = love.graphics.newImage("air.png")} -- image 32x32 pixels
g = {image = love.graphics.newImage("ground.png")} -- image 32x32 pixels
local w, h = 25, 18
map = {}
for y = 1, h do
map[y] = {}
for x = 1, w do
local value = love.math.noise( 0.08*x, 0.2*y)
if value > 0.8 then -- 80% air and 20% ground
map[y][x] = g -- ground
else
map[y][x] = a -- air
end
end
end
end
function love.update(dt)
end
function love.draw()
for y, xs in ipairs (map) do
for x, tile in ipairs (xs) do
love.graphics.draw(tile.image, (x-1)*tileSize, (y-1)*tileSize)

do i need to put a random number generator somewhere?
