[1.7.2][SOLVED] checking an area around the player?

[dark2222]

hi.

 

is there a way to efficient check what blocks there around the player?

i'm trying to make so i update crops around the player right now and i made it work but it breaks about every time i think i'm done and start on something else.

i check a 5x5 area right now but i wan't to make it *x*x* (* = changeable in config)

(here the code i use now https://gist.github.com/henrikse55/c7a33c0154ba146eb2cb)

if theres a more effective way to do so please tell me because i can't find anything about this.

There is definitely a better way.

You should use 3 nested for loops (one each for x, y, z).

It could look something like this:

 

int diameter; // from config or whatever you want
int playerX, playerY, playerZ; // fill those in
for (int x = playerX - diameter; x < (playerX + diameter); ++x) {
    for (int y = playerY - diameter; y < (playerY + diameter); ++y) {
        for (int z = playerZ - diameter; z < (playerZ + diameter); ++z) {
            // do stuff at x, y, z
        }
    }
}

thanks that works a hole lot better then the other code
