(props to @MKleinSB for the oled extension) (i changed it a little, adding diffrent dimensions of images, and making the draw function have a black background instead of a transparent one) ill explain the blocks later. (its very confusing to understand on your own, so i suggest that you should not use it until i explain how it works) ---

Why does it need to be a different thing for OLED? ---

The micro:bit doesn’t have a graphical screen, but a grid of LEDs, and you can’t really show a tile map on it so those blocks aren’t added. But you can add a screen onto the micro:bit, and I think the extensions allows you to make tile maps for the applied screen. Not sure why it’s specifically for OLEDs though. ---

i’m gonna explain the blocks. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/1/1fba2a4876035d38d75c7fd3275bad16a142ab0a.png) sets the tile images. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/4/48c373df55d34265dbd77925c33fb33bce5008d0.png) these (of course) adds and removes tiles. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/2/21a60ecc44ae35cee6c3f4ff818a3d541907a0b1.png) sets the layout of the tilemap, the tiles are represented by ascii characters. (for example, the first tile is " " (space) and the second is “!” and the third is “\*” and so on.) (an example of a layout: ```auto * !!!!!!!!!!! !!! !!!!!!!!!!!!!!!! ``` ) ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/d/d46c24857caac56f117c1dd863ccb64326ef15be.png) gets the image for the tile. (and also, the tile sizes should be 8x8) ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/1/12efb021dc1fcffd154524cdf516ddb0cd35d975.png) gets ascii character from x and y. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/a/a718b28d00a8aa7fe265025c6f89d6a8ed3eec22.png) draws the tilemap on the buffer. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/b/badef876d271ee7f60176f37675b63b51274e929.png) these two are not related to tilemaps. the long one gets two areas and detects if they’re colliding to each other or not. and the short one gets a normal x and y position (which becomes an 8x8 area), and gets a tilemap position, and checks if they collide or not. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/8/8343b26a804e73b8fcdc0377138de416487be59d.png) these set and change the camera position ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/c/c15bcfffc373bf540840a6d4b501ebc645b9aa18.png) this replace the tile (as the an ascii character) at the position. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/6/6311e81639a523d2f2dec1eabe24aeac94b70eea.png) and this, is the same as “get\_tilemap”. (idk why i didnt delete this block.) and thats all! ---
