Isometric endless racing

jdbc

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.

jdbc

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

Nice, looks great! I want to play it!

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

Seems really good for the test run.
A big CongoRatz!!

This is my iso racing apk.

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 - 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.

I have created a new apk with Gideros 2014.10

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.
