A Few Questions [Still Learning]


Lunarius Haberdash

Recommended Posts

I've been quickly picking up coding skill over the last few weeks of intense modding and learning, but there's a lot of simple things that I simply haven't had occasion to stumble on yet.

For instance:
1 - Say I wanted a block to cause an effect if something walked on top of it, where would I start with this?

2 - How can one disable the ability to place a block on top of another particular block?

The general principles that diesieben07 is mentioning are:

 

1) If you want do to something in modding, start by looking at the closest things in vanilla minecraft and see how they accomplish it.

 

2) The approach you take often depends on whether you're making your entirely new thing (block, item, entity) or trying to change an existing one. For your own thing, you can often just extend classes, implement interfaces and override methods as you wish. For vanilla things you need to look for "hooks" such as:

a) Many classes have publicly accessible fields and methods. For example, entity AI is public so you can totally replace it if you wanted.

b) Forge has provided a lot of hooks, especially events but also registries and ore dictiionary, that allow you to intercept and replace vanilla behavior.

c) If you really don't have either of the above, you can use Java reflection to change the access scope of the vanilla fields and methods.

Take a look at vanilla's magma block, which damages entities walking on it.

 

It depends. Is the block being placed added by your mod?

Oooo, that's right, I forgot about the Magma block.  Thank you!

 

And yes.

Well, this particular one is my own added block.  Reflection, I'll admit, have been a bit intimidating for me to consider at this point. I  know I have to look at it eventually, but not quite sure I'm there yet. I wasn't familiar with anything that behaved specifically the way I wanted in Vanilla, as you have to enter Cactus's bounding box before it'll damage you.  Magma, on the other hand, handles that nicely.

 

However, I'm not immediately familiar with anything that doesn't let you place a block on top of it either.

    • i have the decocraft mod and i can see all of them. i can click right click and place the items but as soon as i put it down it disappears. im so sad it doesnt work and i dont know how to fix it. i used cursed forge to launch minecraft as well.
    • Me and my friend wanted to make a custom mod pack hosted on aternos. I downloaded the same mods as the server then started the server and my minecraft and I joined the server without issues. Then I sent the mods to my friend compressed in a zip folder (i don’t know if that has anything to do with the issue). He unpacked it put it in his mod folder and started it but couldn't join the server and got this issue:   internal exception: java.lang.runtimeexception: server not initialized yet! call IMDLib.entityHandler (modid)   Also we are using curseforge launcher to manage the mods on client side. But as I said it works on my side but not with my friend, that’s why it doesn’t make sense   Mod list:   xplosives-1.2.0.jar whisperwoods-1.18.2-2.1.0-forge.jar waystones-forge-1.18.2-10.2.2.jar voicechat-forge-1.18.2-2.4.32.jar trashslot-forge-1.18.2-11.0.3.jar towns_and_towers_forge-1.10.0.1+1.18.2.jar torchmaster-18.2.1.jar ToolBelt-1.18.2-1.18.9.jar toms_storage-1.18.2-1.4.4.jar swingthroughgrass-1.18.2-1.9.1.jar strictly_origins_v5.1_1.18.2.jar starlight-1.0.2+forge.546ae87.jar SpartanWeaponry-1.18.2-3.0.4.jar SimpleQuarry-1.18.2-18.2.5.jar simpleplanes-1.18.2-5.2.2.jar secretrooms-1.18.2-1.1.5.jar right-click-harvest-3.2.0+1.18.2-forge.jar REIPluginCompatibilities-forge-8.0.89.jar RoughlyEnough|tems-8.3.681-forge.jar RegionsUnexploredForge-0.4.1_1+1.18.2.jar TerraBlender-forge-1.18.2-1.2.0.126.jar Recall_Potion_v1.0.3-1.18.2.jar Quark-3.2-358.jar PickleTweaks-1.18.2-6.1.2.jar Pehkui-3.7.11+1.18.2-forge.jar Origins-1.18.2-1.4.1.4-unified.jar naturalist-forge-1.1.1-1.18.2.jar mysticaloaktree-1.18.2-1.2.jar selene-1.18.2-1.17.14.jar MysticalAgradditions-1.18.2-5.1.4.jar MysticalAgriculture-1.18.2-5.1.5.jar MultiMine-1.18.7.jar moyai-1.18.2-1.1.4.jar ModernDynamicSurroundings-5.0.0.4.jar lootbeams-1.18.1-release-july1722.jar journeymap-1.18.2-5.9.7-forge.jar ironfurnaces-1.18.2-3.3.3.jar ironchest-1.18.2-13.2.11.jar industrial-foregoing-1.18.2-3.3.1.6-10.jar titanium-1.18.2-3.5.11-45.jar immersive_armors-1.5.6+1.18.2-forge.jar hardcorerevival-forge-1.18.2-8.0.1.jar HammerLib-1.18.2-18.2.16. jar gravestone-1.18.2-1.0.1.jar geckolib-forge-1.18-3.0.57.jar findme-3.0.6-forge.jar faithfulbackrooms3.0.0.7.jar elevatorid-1.18.2-1.8.4.jar EasyMagic-v3.3.0-1.18.2-Forge.jar PuzzlesLib-v3.5.9-1.18.2-Forge.jar easy_villagers-1.18.2-1.0.11.jar easy_mob_farm_1.18.2-7.1.0.jar DynamicTrees-1.18.2-1.0.4.jar dragonseeker-1.1.1-1.18.2.jar iceandfire-2.1.12-1.18.2.jar Cucumber-1.18.2-5.1.5 jar cloth-config-6.5.116-forge.jar citadel-1.11.3-1.18.2.jar chunkloaders-1.2.8a-forge-mc1.18.jar supermartijn642configlib-1.1.8-forge-mc1.18.jar supermartijn642corelib-1.1.17-forge-mc1.18.jar cave_dweller-1.18.2-1.6.4.jar carryon-1.18.2-1.17.1.12.jar caelus-forge-1.18.1-3.0.0.2.jar BotanyTrees-Forge-1.18.2-4.0.13.jar BotanyPots-Forge-1.18.2-8.1.29.jar Bookshelf-Forge-1.18.2-13.3.56.jar balm-3.2.6.jar AutoRegLib-1.7-53.jar ars_nouveau-1.18.2-2.9.0.jar curios-forge-1.18.2-5.0.9.2.jar Patchouli-1.18.2-71.1.jar architectury-4.12.94-forge.jar almostunified-forge-1.18.2-0.3.10.jar [1.18.2] SecurityCraft v1.9.8.jar
