[1.7.10]Axe that cuts whole tree.

Posted July 25, 201510 yr

So i am starting a new mod. And i just started working with an axe that will cut the whole tree. I didn't write to much code and i only have made it so it destroys blocks of the same type in the vertical position. However i am getting a problem. I defined the "block" as Blocks.log and because of that, the block.DropBlockAsItem drops always as Oak Logs. Is there a way to define all wood material blocks in 1.7.10?

This is the onBlockDestroyed part of the code:

	@Override
public boolean onBlockDestroyed(ItemStack itemstack, World world, Block block, int x, int y, int z, EntityLivingBase entity) {

	block = Blocks.log;


			for(int ypos = y; ypos < ypos+1; ypos++)
			{

				if(world.getBlock(x, ypos+1, z) == block)
				{
					world.setBlock(x, ypos+1, z, Blocks.air);
					block.dropBlockAsItem(world, x, ypos, z, 0, 0);
				}

				else{
					return super.onBlockDestroyed(itemstack, world, block, x, y, z, entity);
				}


			}


	return super.onBlockDestroyed(itemstack, world, block, x, y, z, entity);
}

}

Any help would be appreciated

Use Block#getMaterial to get a Block's Material or use Block#isWood to check if a Block is wood.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Thank you both for the tips.

However changing the code doesn't seem to work.

Only the block that was mined with the axe (and not by code) dropped Birch, the rest was all dropped as Oak Logs.

Right now, i don't get it why this is happening. I thought it was because i set the block as log but apparently no.

This is my new code:

@Override
public boolean onBlockDestroyed(ItemStack itemstack, World world, Block block, int x, int y, int z, EntityLivingBase entity) {


			for(int ypos = y; ypos < ypos+1; ypos++)
			{

				if(world.getBlock(x, ypos+1, z).isWood(world, x, ypos+1, z))
				{
					block.dropBlockAsItem(world, x, ypos, z, 0, 0);
					world.setBlock(x, ypos+1, z, Blocks.air);
				}

				else{
					return super.onBlockDestroyed(itemstack, world, block, x, y, z, entity);
				}


			}


	return super.onBlockDestroyed(itemstack, world, block, x, y, z, entity);
}

Thank you for that but i managed to make a much simplier code. But that may be helpfull for something else in my mod.

Instead of checking by ignorin blocks i chechked if the block in top of what i mined is a tree

that is not going to work well for those larger oak trees with branches, let alone for dark oak (2x2 + irregular log parts on sides) or jungle trees. or acacia. basically the solution is birch/spruce only.

what others have done (there are a few existing mods that make axes do what you want) is do a backtracking search up and sideways to find all logs that comprise a tree. reason one is that that way they break all those logs for a complete effect. reason two is that they are then able to damage the axe for a number of logs broken instead of just one.

but that is actually a simple task (even though the branch-logs sometimes don't touch the base (vertical) logs; you can allow for one leaf block between logs). the hard task would be taking down the leaves. because if you write a bad algorithm, you could clean up entire forest with one swing of that axe.

New Forum Design/Update: Issues and Suggestions

Unfortunately, it seems that Invision has decided that everything is locked down and no longer customizable.
Their attitude to anyone who wants to edit anything is 'Just accept it we know best and screw you for even insinuating that you want to customize your own site'
So there isn't much we can do about the layout of actual features.
Best bet for the editor is that psudo markdown works, so typing ` around words make code blocks.
Only options is to start writing bespoke modifications to the forum's php code itself, which I really don't want to do.
I would of stayed on v4 but the version of PHP that it supports is going EOL and Invision has stated they have no intentions of upgrading it.
They also removed the central community for finding plugins/community addons.
Overall it is my feeling that they are intentionally trying to kill off self-hosting communities by removing features and locking things down, in an effort to force everyone into using their paid hosting services.

My HOPE is that someone in the overall forum community will write an exporter for Invision to something like SMF. Which is what we were originally on before old team members decided enterprise software is better.

Yes i will be uploading the mod to curse forge and modrinth you can already find a early build

https://www.curseforge.com/minecraft/mc-mods/wemmbus-style-orbital-strike-cannon
https://modrinth.com/mod/wemmbus-style-orbital-strike-cannon

hopefully 1.21.5 fabric will be out by the weekend also please note that there is a lot more features im adding like cubic metres orbital arrow cannon type shot (basically a stab shot but with insta kill arrows)

@FoxyWoxy do you potentially have an estimated time for fabric 1.21.5 and what will it be posted on (modrinth, etc.)

I don't know that either - newer worked with Invision Community 😕

The Forum/Guides show a customized toolbar:
https://invisioncommunity.com/4guides/themes-and-customizations/editor-and-emoticons_327/customizing-editor-toolbars-r132/
But I have no idea if this applies to v5

Regarding the Forum, "Mark all as read" seems to be hidden as default but is available if I click on my profile:
https://invisioncommunity.com/forums/topic/481218-fix-for-unreadmark-read/

I saw that it works here and also fixes the one unread thread mentioned in my first post - so I had just overlooked it

The toolbar changes are just QoL - if there is no way to change it at the moment, that's fine
