Map Collision Blocks

Hello! Just asking does anyone know how to have tiles that are in a map be solid objects that players and project tiles can't got through? Let me know please. Thanks.

Hey! Here's how you can make tiles in your map solid so the player and projectiles can't go through them:

// List of solid tile IDs solidTiles = [1] // Add other solid tile numbers if needed

// Function to check if a tile is solid function isSolid(x, y) tx = floor(x / map.tileWidth) ty = floor(y / map.tileHeight) tile = map.getTile("layer", tx, ty) return solidTiles.indexOf(tile) >= 0 end

Then before you move the player or projectile, just check like this:

// For player movement if not isSolid(player.x + dx, player.y) then player.x += dx end

if not isSolid(player.x, player.y + dy) then player.y += dy end

// For projectile collision if isSolid(projectile.x, projectile.y) then projectile.active = false end

Just make sure to replace "layer" with the name of your tile layer (like "ground" or "walls"). Let me know if you want help with anything else! :)

So should I put this in a separate file or the main file?

Good question! You can just put the code in your main file (like main or whatever you're using for game logic).

Here’s how to organize it:

Put the solidTiles = [...] and function isSolid(x, y) at the top of your main file, maybe under your global variables.

Use the isSolid(...) checks inside your player or projectile update code, wherever you're handling movement or collisions.

No need for a separate file unless you want to organize your project more later.

Let me know if you want help placing it in your existing code! :)

Yeah I might need a bit help here, Imma bit confused

No problem at all! Just let me know what part you're stuck on — like where to put the function, how your player movement works, or what tile layer you're using — and I can help you piece it together.

If you want, you can copy and paste part of your code and I’ll help fix it up with the solid tile logic added in! :)

It's a bit weird but here it is:

init = function()
  mode = "intro"
  
  initPainter()
  initSprinter()
 initShielder()
end

update = function()
  if mode == "intro" then
     updateIntroScreen()
    end
  if mode == "title" then
    updateTiltleScreen()
  elsif mode == "select" then
     updateSelectScreen()
  end
  if mode == "painterplay" then
    updatePainter() 
end
if mode == "sprinterplay" then
  updateSprinter()
end
if mode == "shielderplay" then
  updateShielder()
end
end

draw = function()
  screen.clear()
  if mode == "intro" then
     drawIntroScreen()
    end
  if mode == "title" then
 drawTitleScreen()
  elsif mode == "select" then
   drawSelectScreen()
  end
  if mode == "painterplay" then
    drawPainter()
end
if mode == "sprinterplay" then
  drawSprinter()
end
if mode == "shielderplay" then
  drawShielder()
end
end
