    Isometric endless racing

    edited October 2015 in Game & application design
    This is a video of my isometric racing prototype. I have only used sprites as tiles and lua tables to create infinite and random blocks on the road. Isometric tiles from Kenney: http://kenney.nl/assets/isometric-city

    Controls are easier: tap to accelerate and do not touch screen to brake.

      I have used these two helper functions:
      -- Get isometric coordinates from cartesian coordinates (x,y)
function twoDToIso(x, y)
 
	local isoX = x -y
	local isoY = (x + y) / 2
 
	return isoX, isoY
end
 
-- Get cartesian coordinates from isometric (isoX, isoY)
function isoTo2D(isoX, isoY)
 
	local x = (2 * isoY + isoX) / 2
	local y = (2 * isoY - isoX) / 2
 
	return x,y
end
      Rendering with isometric coordinates and collision in converted 2d coordinates. Tile width and tile height are 64 bits.
      To create the map I have generated 12 blocks and they are added to scene from top to down and left to right. First 6 blocks do not allow transversal roads.
      -- Rendering blocks
	for a=0,12 do
 
		if (a > 5) then
			num = 6
		end
 
		local block = Block.new(num)
		block:setPosition(twoDToIso(0, TILE_HEIGHT * a))
		table.insert(block_list, block)
		road:addChild(block)
 
		num = num -1
		if (num < 0) then
			num = math.random(0,3)
		end
	end

      Tomorrow I will upload to the forum a sample apk to test it.

      Seems really good for the test run.

      really cool! :)
      it seems a bit "heavy" on galaxy s2 when speed is high: I don't know if it's due to this known bug on android - https://github.com/gideros/gideros/issues/22

      I would try "inverting" the controls to promote adrenaline :D - auto accelerate and press to break

      Yes you are right, the problem with "heavy" problem it is Gideros version (2015.09).

      I have tested in my Bq Aquaris again with a very previous version (2014.01) and it works smoothly.

      What happens with lastest versions that have worse performance?

      I go back to previous versions at least for Android.

      Tried it, nice! A bit stuttery when you go fast on my Nexus 6, and the bitmaps are a bit blurred.

      Are you using a spritesheet? If not that can speed things up. And the @2, @3 feature for crisp bitmaps is a winner.

      This is just a prototype, I am using 64x64 isometric tilemaps, so I know that bitmaps are blurred with high screen resolutions. Every bitmap are stored as individual file, I should use spritesheet to improve performance.

      I suppose I will buy Kenney art to get 128x128 images (or even 256x256) from vectorial ones (9$ all assets):

      Hey, pretty cool mate. I would recommend shelling out the few bucks for the Kenney Assets, they are fantastic! You also get all future updates to the pack too which makes it even better :)

      I have bought Kenny assets. Isometric tiles that I need are provided as 3D models, I must convert them to images.

      Invert controls, tap to brake and automatic acceleration could be fine, thanks for your ideas.

      I tried the other one, it's smoother but it also seems "slower" than the first one. If you put an fps counter I could tell you better. :)

      I have increased now the speed and difficulty so. Controls are inverted, tap to brake and speed up if you do not. I should improve the collision system but its playable for the moment.

      Next days will be first version in Google Play.

      I have just published "Speedy Road" in Google Play. In few hours it will available.
