Code	/* These techniques are free to use as long as you give credit somewhere in the code or in the game, thank you! WASD or Arrow keys to move, R to restart, Z to toggle zoom Left and Right click to add or remove blocks GUI * If a square is blue, that means it is within the collision indexing of the player If a square is green, that means it is a block being tested for collisions If a square is black, nothing is being done to it except drawing How it works * So first it rotates the worldData array values, I made it sideways to reduce confusion. Then, it loads a 2d array of block data based on that rotated array. Next, it finds the player's position as a 2d index for a 2d array. Once that has been done, it takes a chunk of the world array and renders it based on the players position. Finally, it uses the same technique of accessing the player position as an index and test for collisions based on indexing from the player. Finally, it applies those collisions. Now I can load over 4000 blocks and have it run flawlessly at 60 fps. A Possible Improvement (Not Mandatory) * You could render everything to images instead of drawing rects at each block location, but in this project drawing rects works fine. You would do this by making a function (Img) and drawing the rect normally but at the coordinate 0, 0. var Img = function() { fill(0); rect(0, 0, 20, 20); }; Then, you would use return get(x, y, w, h); to render it as an image var Img = function() { fill(0); rect(0, 0, 20, 20); return get(0, 0, 20, 20); }; Finally, in order to call it as an image, you have to make an instance of the function once it has returned the image. Two ways to do this are below var Img = function() { fill(0); rect(0, 0, 20, 20); return get(0, 0, 20, 20); }; var img = Img(); //actual image image(img, x, y, w, h); /////////////////////// var Img = (function() { fill(0); rect(0, 0, 20, 20); return get(0, 0, 20, 20); })(); //a function that calls itself and accesses the image image(Img, x, y, w, h); / frameRate(60); //sets the target fps to 60 /*
