I am having trouble with loading specific parts of an array around my player. I am doing this because ~12,000 blocks getting loaded at once doesn't seem like a good option.
In my code currently the array is loaded with this code:
for (var i = 0; i < levels[level].length; i++) {
for (var j = 0; j < levels[level][i].length; j++)
{
switch (levels[level][i][j]) {
Then I list a strand of text like "b" for example like this:
case "b":
blocks.push(new Block(j * blockwidth, i * blockheight, "block"));
break;
I have tried constraining the levels[level].length to the players like this;
for (var i = 0; i < constrain(levels[level].length,player.y-player.y,player.y+player.y+30); i++) {
for (var j = 0; j < constrain(levels[level][i].length,player.x-player.x,player.x+player.x+30); j++) {
switch (levels[level][i][j]) {
It had seemed to work until I moved around and saw that the view outside my player's spawn was unloaded
(I'm working on Khan Academy) here is a link to it:
(copy some of the code examples and use ctrl+f in the code box to find where it is in the code)
So I figured it out
for(var i = round(player.y/blockheight-1); i < round(player.y/blockheight)+2;i++){
for(var j = round(player.x/blockwidth)-1; j < round(player.x/blockwidth)+2;j++){
switch(levels[level][i][j]){
while doing this I figured out
when loading an array
example
for(var i = -y1; i < +y1;i++){
for(var i = -y1; i < +y1;i++){
when the y1 is - negative (-y1) and connected to a player's y pos it is negative y
when the y1 is + positive (+y1) and connected to a player's y pos it is positive y
when the x1 is - negative (-x1) and connected to a player's x pos it is negative x
when the x1 is + positive (+x1) and connected to a player's x pos it is positive x
