I am making a tetris clone in love2d (lua) for practice. And what I am trying to do is to make the collins with the walls.

Note:the tetris pieces are made out of tiles that each one has a relative positions to the piece’s position that is stored inside of a table.

Here’s how I implemented the wall collisions

function tetros.wallLeftCollision(x)

  for i, c in pairs(tetros.shapes[v.shape].angles[v.angle].cubes) do

    local cx= c.x+x

    if cx-1 <= v.window.x then

      return false

    else

      return true

    end

  end

end

x: is the piece’s x position

“tetros.shapes[v.shape].angles[v.angle].cubes”: is the table that contains the relative positions of the tiles that forms the piece

“cx= c.x+x”: here I convert the relative position to a normal position

“cx-1” I just shift the position slightly to the left

“v.window.x” this is the x position of the space where the pices fall (idk how to call it)

But when I run the code it apparently choses a random tile and compare it instead of comparing all the tiles.

what should happen here is the code checks if the position of any tile in the tetris piece is 1 pixel to the right pf the border and the it returns true.

After that I tried to do a bunch of research to see why it was happening but all I found is that it should work as it is.

Note:Please consider the fact that I have no programming experience beside Minecraft commands and I am just getting started
