[1.6.2]Clear cube-shaped area in world


kc9zda

Recommended Posts

I am trying to put a platform for the player to spawn on and I want all of the platform to be at least visible and I want the player to be able to spawn on it. Currently, if it is in the side of a hill, it is useless, if it is under a tree, the player spawns on top of the tree instead of on the platform. That is why I want to clear a 9 block high area above the platform. I have code to do it, but it doesn't work. I have three nested while loops (one for x, y, and z) and it uses World.setBlockToAir. It only seems to clear either one part of a row or none at all.

for(x=-3;x<=3;x++) {

  for(y=-3;y<=3;y++) {

    for(y=-3;y<=3;y++) {

      world.setblock(x,y,z);

    }

  }

}

 

Seriously, this is basic java.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I had something similar to what Draco18s had but each is in a different method:

 

private void clearAreaCube(int x, int z, int xD, int zd, int y, int yd,

World w) {

int i = 1;

 

while (i <= xD) {

clearColumnRow(x+i, z, zd, y, yd, w);

i++;

}

}

 

private void clearColumnRow(int i, int z, int zd, int y, int yd, World w) {

int j = 1;

 

while (j <= zd) {

clearColumn(i, z+j, y, yd, w);

j++;

}

}

 

private void clearColumn(int i, int j, int y, int yd, World w) {

int k = 1;

 

while (k <= yd) {

w.setBlockToAir(i, j, y+k);

k++;

}

        }

 

xD, yd, and zd are the change in x, y and z respectively. I originally had three nested while loops and it only cleared one row of blocks. I just tried the alternative code that was suggested, and it cleared no more than last time. Both pieces of code seemed to clear trees completely from the cube, but I just think that they didn't spawn. After that, I took out the clearing code and placed the structure on the first level that could see the sky (it works in most worlds). Thanks for your help anyway.

I can't see any obvious mistake in that code.

What values do you call this with ?

 

Bear in mind that in World#setBlockToAir(int,int,int), the middle parameter is the height value.

(Just saying this because your "clearColumn" is clearing horizontally)

 

It might also be worth making your world instance a field of this class, so you don't have to pass it through all those methods.

    • Thank you for your answer ! Unfortunatly i have the same problem when i use setPos() public static int movingfunction(CommandContext<CommandSourceStack> context){ CommandSourceStack source = context.getSource(); if (!(source.getEntity() instanceof ServerPlayer)) { return 0; } ServerPlayer player = (ServerPlayer ) source.getEntity(); double moveSpeed = 0.5; for (int i =0; i<10000;i++) { LOGGER.info("running for the {} time", i); double x = player.getX() + player.getViewVector(1.0f).x * moveSpeed; double y = player.getY(); double z = player.getZ() + player.getViewVector(1.0f).z * moveSpeed ; Vec3 movementVec = new Vec3(x, y, z); LOGGER.info("x ={} y ={} z ={}", x, y, z); player.setPos( movementVec); } return 1; } With the logs i can see that x and z are increasing but once again my player is not moving. is there a function to use to sync the server and the client ? I also tried to use LocalPlayer instead of ServerPlayer but my code would stop when i got the object. Also i will change a bit the main topic but is there a way to similate key press ? i found KeyBinding.setKeyBindState on others post but it look like there is no more KeyBinding in 1.20   I found this code : KeyMapping.click(Minecraft.getInstance().options.keyUp.getKey()); But it doesn't seems to work   And i found this one : Minecraft.getInstance().options.keyUp.setDown(true); wich works but doesn't exactly do what i want , it doesn't release the key so for exemple i can't make him run. Minecraft.getInstance().options.keyUp.setDown(true); Minecraft.getInstance().options.keyUp.setDown(false); Minecraft.getInstance().options.keyUp.setDown(true); doesn't make him run
