Posted March 21, 20178 yr Working on a terrain scanner that starts scanning from a block position:1 north a east, b west & 2 south a east, b west for loop on directions (not sure its accuracy yet) I have made a class for it as utility, where it checks each block position scanning if its in ground or in air. if its in ground it should go up through a loop in position coordinates till it it is no more ground and record the top gound(dirt/grass/stone), its its in the air(air/log/leaf) bring the position coordinates down till there is no more air and the under the last block of air record the ground block Here is my git, and the specific method i am dealing with and now ill show you what the problem is [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:grass} POS BlockPos{x=90, y=63, z=257} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:dirt} POS BlockPos{x=94, y=63, z=257} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:stone} POS BlockPos{x=99, y=63, z=257} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:stone} POS BlockPos{x=105, y=63, z=257} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:stone} POS BlockPos{x=105, y=63, z=262} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:stone} POS BlockPos{x=104, y=63, z=262} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:stone} POS BlockPos{x=102, y=63, z=262} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:dirt} POS BlockPos{x=99, y=63, z=262} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:dirt} POS BlockPos{x=95, y=63, z=262} [00:38:45] [Server thread/INFO] [testmod]: BLOCK Block{minecraft:dirt} POS BlockPos{x=90, y=63, z=262} I have checked where the stones are too, in-closed by dirt and grass Edited March 21, 20178 yr by clowcadia to note
March 21, 20178 yr There are so many things wrong here....Why are you using | instead of ||? Anyway, your problem is thus: 1a. for(int u = 1; b. isGround(pos.up(u)); c. u++){ 2. if(isAir(pos.up(u))) { 3. floor = pos.up(u-1); 4. } 5. } Line 1a executes: u = 1 Line 1b executes: the block is dirt, returns true Line 2 executes: returns false (it was ground, so it cannot be air) Line 4 executes [end of loop, returning to top] Line 1c executes: u = 2 Line 1b executes: the block is air, returns false Line 5 executes [end of block] And you would know this without wasting my time if: a) you doodled on some paper and tried running through it yourself b) you used the debugger that God gave you and watched your code execute Edited March 21, 20178 yr by Draco18s 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.

March 21, 20178 yr Author tried this bust still same result for(int u = 1; isGround(pos.up(u)); u++){ if(isAir(pos.up(u+1))) floor = pos.up(u); }
March 21, 20178 yr What happens if a block is neither air nor ground?

March 21, 20178 yr Author based on this, it should technically register as something.. though private boolean isGround(BlockPos pos){ return (getBlock(pos) == Blocks.DIRT || getBlock(pos) == Blocks.GRASS) || getBlock(pos) == Blocks.STONE; } private boolean isAir(BlockPos pos){ return getBlock(pos).isAir(getIBS(pos),this.world,pos) || ( getBlock(pos) == Blocks.LOG || getBlock(pos) == Blocks.LOG2) || (getBlock(pos) == Blocks.LEAVES || getBlock(pos) == Blocks.LEAVES2); } i am missing tall grass but yea

This is a list of all vanilla blocks. You're missing more than just tall grass.
March 21, 20178 yr Author I know, i have a similar page open, but i am just testing it in somewhat controlled enviorment, its testing a 15x15 area in a forest, yes there are flowers but i dont think there is that many flowers to give me the results of air and stone of such amount
March 22, 20178 yr 11 minutes ago, clowcadia said: Question: can i edit code while i debug? with this specific situation If you mean "Can I edit code while running the game", it depends on your IDE (but most of them have this feature). Eclipse has a little green beetle button next to the play button that runs the game in debug mode. While in debug mode, any non-breaking edits will be instantly noticeable in-game. If you make a breaking edit, Eclipse will tell you that you need to relaunch the game before the edit has an effect. I'm not sure about Intellij though. Edited March 22, 20178 yr by TheMasterGabriel
March 22, 20178 yr Should be able to with IntelliJ too. But yes, it depends on the IDE. Mind, there are some bits of your code that even if you make non-breaking edits, won't affect the running code, because that part already ran and won't run again. E.g. changes to constructors, your main class, etc. The objects aren't reinitialized, just that their methods are updated.

March 22, 20178 yr Author yes just want to try and fix the issues, in my head sudo wise its meant to work right but i am missing something

You are incorrectly determining the end of the loop and the set-floor position booleans. If it finds a floor, then the loop exits, right? In which case make it so that when it sets the floor the loop exits. There's a dozen ways to do this and all of them fail proof. You're trying to use two checks that don't have an inverse relationship (i.e. isGround(state) == !isAir(state) is not true for all possible blockstates). Again: What happens if the column at the search location contains a tree?

March 22, 20178 yr Author When it is a tree like logs or leafs it identifies as air, should be the code if not that what i have edited to identify
March 23, 20178 yr How about tall grass? Flowers? Fences? Farmland? Cobblestone? Gravel? Sand? Sandstone? Water? Snow? Ice? Arbitrary mod-added block? Your if-statements are poorly defined as "isAir() == !isGround()" is not a tautology. What happens if your code encounters a cave (stone, air, stone)?

March 27, 20178 yr Author finally solved the issue, but now i am goign to take ur advice on the rest of the forestry stuff but i dont know how to find the flower block as getBlock(pos) == BlockFlower.; does not display options like Blocks. does
March 28, 20178 yr Author there is only 2 types of flowers they have other varients that make them up as different flowers, but in general all but one flower is REDFLOWER and the one is YELLOWFLOWER in the blocks

March 28, 20178 yr Author thank you, i just ran into it, and discovered through console prompts. would u say a double plant is a 2 block plant/flower?

March 28, 20178 yr Well, the crash report says the ArrayList is size one, which means it did have a 0 index. But if it doesn't, that means you're trying to call it on an empty ArrayList. Post the code where you create and use the list.
March 28, 20178 yr 2 minutes ago, clowcadia said: if(treeRoots.get(0)!=null){ The crash is caused by calling get, a null check won't help because it happens after the method is called.
