[updated subject to be more specific]

 

Okay, so I have created an EntityTiger that is essentially a re-textured vanilla wolf, and it works perfectly (basically behaves like a wolf in that it is passive unless attacked, can be tamed, hunts sheep on its own, etc.)

 

I want to make a sub-class EntityManEatingTiger which extends EntityTiger but basically is always hostile and will attack a player on sight.  I thought I could do this by setAngry(true) and setting target to the player (I realize this isn't really good practice for multiplayer, but will fix that later).  I also have setTamed(false). 

 

So I have an untamed, angry tiger with player as the target.  It does in fact look angry (red eyes texture), and it follows my player and leaps at it just like it is attacking me.  However, it doesn't actually do any damage (not a real attack).  If I hit it though, then it will attack me for real.

 

So I'm missing something -- how do you make it actually attack rather than follow me with red eyes?

 

Here are the two classes.

Okay, I had some success by changing the way I reference the player.

 

Originally I had:

 

super.setAttackTarget(Minecraft.getMinecraft().thePlayer);

 

Which I replaced with:

 

hunted_player = this.worldObj.getClosestVulnerablePlayerToEntity(this, 32.0D);

super.setAttackTarget(hunted_player != null && this.canEntityBeSeen(hunted_player) ? hunted_player : null);

 

 

 

I guess I'm okay now that it works, but I like to understand code that doesn't behave how I expect.  Why would the original code make the entity look like it attacked (but with no damage) whereas the second version works?

 

I'm guessing it has to do with server side versus client side?  Maybe the first one wasn't properly updating the server version of the player object so what looked like an attack on the client side didn't really cause damage?

 

client - server stuff is still something I mess up a lot ...

      Dependency Issues with Custom Portal API [Forge]

      By BananaRebel · Posted

      Hi,  I'm using Forge 47.3.0 for Minecraft 1.20.1 I apologise if this is obvious I am very new to modding for Minecraft. I sucessfully made a mod that launched without errors or crashes (without it doing anything) but in order to add the features I need, I need to add "Custom Portal API [Forge]" as a dependency. However no matter the way I've tried to acheive this, it crashes. I am pretty sure it's not the way I'm putting it in the repositories, the dependencies or the way I'm refrencing it, as I've a hundred diffrent combinations and multiple Maven methods. And on all those diffrent variations I still get this crash: pastebin.com/UhumzZCZ Any tips would be invaluable as I've been loosing my mind over this!

      Forge 54.1.1 Missing Textures please help

      By xLorkin · Posted

      Hi, i'm really having problems trying to set the texture to my custom item. I thought i'm doing everything correctly, but all i see is the missing texture block for my item. I am trying this for over a week now and getting really frustrated. The only time i could make the texture work, was when i used an older Forge version (52.0.1) for Minecraft (1.21.4). Was there a fundamental change for textures and models somewhere between versions that i'm missing? I started with Forge 54.1.0 and had this problem, so in my frustration i tried many things: Upgrading to Forge 54.1.1, created multiple new projects, workspaces, redownloaded everything and setting things up multiple times, as it was suggested in an older thread. Therea are no errors in the console logs, but maybe i'm blind, so i pasted the console logs to pastebin anyway: https://pastebin.com/zAM8RiUN The only time i see an error is when i change the models JSON file to an incorrect JSON which makes sense and that suggests to me it is actually reading the JSON file.   I set the github repository to public, i would be so thankful if anyone could take a look and tell me what i did wrong: https://github.com/xLorkin/teleport_pug_forge   As a note: i'm pretty new to modding, this is my first mod ever. But i'm used to programming. I had some up and downs, but through reading the documentation, using google and experimenting, i could solve all other problems. I only started modding for Minecraft because my son is such a big fan and wanted this mod.

      New Website for Quick & Easy Minecraft Info

      By MinecraftSearch · Posted

      Hello fellow Minecrafters! I recently returned to Minecraft and realized I needed a wiki that displays basic information easily and had great user navigation. That’s why I decided to build: MinecraftSearch — a site by a Minecraft fan, for Minecraft fans. Key Features So Far Straight-to-the-Point Info: No extra fluff; just the essentials on items, mobs, recipes, loot and more. Clean & Intuitive Layout: Easy navigation so you spend less time scrolling and more time playing. Optimized Search: Search for anything—items, mobs, blocks—and get results instantly. What I’m Thinking of Adding More data/information: Catch chances for fishing rod, traveling villager trades, biomes info and a lot more. The website is still under development and need a lot more data added. Community Contributions: Potential for user-uploaded tips for items/mobs/blocks in the future. Feature Requests Welcome: Your ideas could shape how the wiki evolves! You can see my roadmap at the About page https://minecraftsearch.com/about I’d love for you to check out MinecraftSearch and see if it helps you find the info you need faster. Feedback is crucial—I want to develop this further based on what the community needs most, so please let me know what you think. Thanks, and happy crafting!
