A block that spreads over every block but air?

[Looke81]

Hi everyone i have made a block that can spread over the top of grass next to it and i tried to do this with all blocks by using block not Blocks.grass but of course this uses air so it spreads in the air i only want it to spread over the surface is there anyway i can make it spread over every block but air?

 

update tick

 

public void updateTick(World p_149674_1_, int p_149674_2_, int p_149674_3_, int p_149674_4_, Random p_149674_5_)

            {

                if (!p_149674_1_.isRemote)

               

                if (p_149674_1_.getBlockLightValue(p_149674_2_, p_149674_3_ + 1, p_149674_4_) >= 9)

                    {

                        for (int l = 0; l < 45000; ++l)

                        {

                            int i1 = p_149674_2_ + p_149674_5_.nextInt(3) - 1;

                            int j1 = p_149674_3_ + p_149674_5_.nextInt(5) - 3;

                            int k1 = p_149674_4_ + p_149674_5_.nextInt(3) - 1;

                            Block block = p_149674_1_.getBlock(i1, j1 + 1, k1);

 

                            if (p_149674_1_.getBlock(i1, j1, k1) == block && p_149674_1_.getBlockMetadata(i1, j1, k1) == 0 && p_149674_1_.getBlockLightValue(i1, j1 + 1, k1) >= 4 && p_149674_1_.getBlockLightOpacity(i1, j1 + 1, k1) <= 2)

                           

                                p_149674_1_.setBlock(i1, j1 + 1, k1, this);

                            }

                           

                           

                        }

                    }

Wah? what is this?

 

Always, always use good and simple to understand names

[Looke81]

ok thats not very usefull but il be honest i did take some of it from the mycelium class so yea the names arnt very easy to understand

[Looke81]

better?

 

 

public void updateTick(World world, int x, int y, int z, Random random)

            {

                if (!world.isRemote)

               

                if (world.getBlockLightValue(x, y + 1, z) >= 9)

                    {

                        for (int l = 0; l < 45000; ++l)

                        {

                            int i1 = x + random.nextInt(3) - 1;

                            int j1 = y + random.nextInt(5) - 3;

                            int k1 = z + random.nextInt(3) - 1;

                            Block block = world.getBlock(i1, j1 + 1, k1);

 

                            if (world.getBlock(i1, j1, k1) == block && world.getBlockMetadata(i1, j1, k1) == 0 && world.getBlockLightValue(i1, j1 + 1, k1) >= 4 && world.getBlockLightOpacity(i1, j1 + 1, k1) <= 2)

                           

                                world.setBlock(i1, j1 + 1, k1, this);

                            }

                           

                           

                        }

                    }

             

[Jacky2611]

yeah, way better.

 

public void updateTick(World world, int x, int y, int z, Random random)
            {
                if (!world.isRemote)
                   

                        for (int i = 0; l < 45000; ++l)
                        {
                            int i1 = x + random.nextInt(3) - 1;
                            int j1 = y + random.nextInt(3) - 1;
                            int k1 = z + random.nextInt(3) - 1;
                            Block block = world.getBlock(i1, j1 + 1, k1);

                            if (world.getBlock(i1, j1, k1) != Blocks.air){
                           
                                world.setBlock(i1, j1 + 1, k1, this);
                            }
                           
                           
                        
                    }

try something like thisthis

[Looke81]

no this hasn't worked its still doing the same thing

[Jacky2611]

what? what does it do/not do?

[Looke81]

ive done this and its fixed the problem but now it is spreading down

 

  if (world.getBlock(i1, j1, k1) ==block &&  (world.getBlock(i1, j1, k1) != Blocks.air)){

                               

                                world.setBlock(i1, j1 + 1, k1, this);

                            }

[Jacky2611]

yeah, i know.

 

                            int i1 = x + random.nextInt(3) - 1;
                            int j1 = y + random.nextInt(3) - 1;
                            int k1 = z + random.nextInt(3) - 1;
                            Block block = world.getBlock(i1, j1 + 1, k1);

                            if (world.getBlock(i1, j1, k1) != Blocks.air){
                           
                                world.setBlock(i1, j1 + 1, k1, this);
                            }

 

j1 is the y coordinate (height) from the block it spreads to, right?. it basically is the blocks current location plus a random number.

ok, what is this random number?

  Quote

int j1 = y + random.nextInt(3) - 1;

it is either:

0

1 or

2

minus 1. his means that it can spread

-1(down)

0(same y)

+1(up)

 

 

 

sry accidentaly had a 2 there, my fault, fixed it secs before your post

[Looke81]

wait i dont understand what do i need to change to 0?

[TheGreyGhost]

By crikey dude, where did that 45000 come from?  You will be running that setBlock loop 45000 times for every block you add.

 

                        for (int l = 0; l < 45000; ++l)
                        {

 

 

Another question  - what's the point of having a random value for y?

 

And in fact, why are you using random values for x and z as well?  Why not just try the four adjacent blocks?

 

This link might help you a bit, perhaps?

[Jacky2611]

guess he wants that his block spreads as fast as possible:D

 

if you want that your block spreads only upwards you have to remove the -1 from the new y(j1) coordinate and change the 3 to a 2

I might have to add that to my signature. +3 reddit gold!

[Looke81]

I wont have it spreading that fast but i want it to spread quickly for testing thats all

[Looke81]

"if you want that your block spreads only upwards you have to remove the -1 from the new y(j1) coordinate and change the 3 to a 2"

 

No i want it so that it dosen't spread upwards

No i want it so that it dosen't spread upwards

it shouldn't spread up/down?

than you can us your block y coordinate 1:1 for your new blocks y(=j1) coordinate.

[Looke81]

i dont know if i have done the right thing but this dosen't work.

 

public void updateTick(World world, int x, int y, int z, Random random)

            {

                if (!world.isRemote)

               

                if (world.getBlockLightValue(x, y + 1, z) >= 9)

                    {

                        for (int l = 0; l < 45000; ++l)

                        {

                        int i1 = x + random.nextInt(3) - 1;

                            int j1 = y + random.nextInt(3) - 1;

                            int k1 = z + random.nextInt(3) - 1;

                            Block block = world.getBlock(i1, j1 + 1, k1);

 

                            if (world.getBlock(i1, j1, k1) != Blocks.air){

                         

                                world.setBlock(x, j1 + 1, z, this);

                            }

                        }

                        }

                    }

[Jacky2611]

int j1=y;

[Looke81]

now this is just spreading up

 

public void updateTick(World world, int x, int y, int z, Random random)

            {

                if (!world.isRemote)

               

                if (world.getBlockLightValue(x, y + 1, z) >= 9)

                    {

                        for (int l = 0; l < 45000; ++l)

                        {

                        int i1 = x + random.nextInt(3) - 1;

                        int j1=y;

                            int k1 = z + random.nextInt(3) - 1;

                            Block block = world.getBlock(i1, j1 + 1, k1);

 

                            if (world.getBlock(i1, j1, k1) != Blocks.air){

                         

                                world.setBlock(i1, j1 + 1, k1, this);

                            }

                        }

                        }

                    }

Please use [ code ] tags.

 

It's just spreading up because you're setting the block above with your

j1 + 1

. Change that to just

j1

.

 

In fact, remove

j1

altogether and just use

y

.

 

Also, as has been pointed out, running 45000 iterations is a bit overkill.

[Looke81]

I dont think you understand i want it to spread over the top of blocks next to it if i remove the +1 it will just delete that block and replace it with itself

[Looke81]

anyone else think they might have a solution?

[Looke81]

anyone?

[MultiMote]

I dunno, it works

 

    public void updateTick(World world, int x, int y, int z, Random random)
    {
            if (!world.isRemote && world.getBlockLightValue(x, y + 1, z) >= 9)
                for (int i = 0; i < 4; ++i)
                {
                    int randX = x + random.nextInt(3) - 1;
                    int randY = y + random.nextInt(3) - 1;
                    int randZ = z + random.nextInt(3) - 1;

                    if (world.getBlock(randX, randY, randZ) != Blocks.air)
                        world.setBlock(randX, randY, randZ, Yormod.yourblock);
                }
    }

[Looke81]

no i want it to spread on top of adjacent blocks not to be abble to grow ontop of itself
