Block events in forge? (BlockBreak, BlockPlace, Explosions etc)

[epicsquare]

Hi,

 

How would I get these events in Forge. Coming from bukkit, I would like to port over some of my mods, and I need those events(Block Break, Block Place, Entity Explode). Surprisingly, I have not been able to find any kind of information online about server only mods for forge. Does anyone have any information on this too?

 

Thanks a lot!

keepcalm has a small api for this:

 

https://github.com/keepcalm/BlockBreak

 

Now I have been trying it myself but I can not get it working due to the methods not existing that are shown in the readme, Give that a try and let me know how you get on because I need to use it myself aswell.

Now as for adding blocks etc..I dont know

 

Anyone else that can help would be great.

[epicsquare]

Yeah, I found his little api too, but that covers only but a third of what I need. I'll take a look at it later, but hopefully there is a more universal solution to this. Thanks anyway!

 

EDIT: I got his API to build and all, but it doesn't seem to actually work. I'm not fully sure if I'm using it properly though, as in I'm not sure how to integrate it into the source. I just kind of tossed his folder into <mcproot>/src/minecraft and then registered a container class on the event bus which was:

 

public class EventHookContainerClass {

 

@ForgeSubscribe

public void BlockBreak(PlayerBreakBlockEvent e)

{

System.out.println("Break!");

}

}

 

However this was not called when block were broken.

Did you initialize it?

 

MinecraftForge.EVENT_BUS.register(new ForgeEventHandler())

 

Again this is what he says to do on github, but for me again there is no ForgeEventHandler??

 

Edit:

 

Sorry I think I just realised im supposed to create that ForgeEventHandler class?? As you said you registered your own class on the even bus

[epicsquare]

Yes that's right I assumed I create my own event container class (as in my reply) and registered that. Please let me know if it works for you.

[keepcalm]

That's right, but you need to ensure FML is loading the coremod. Ninjar (for the coremods folder) coming soon

[xxxgamer]

So now that ive changed the code to look like this:

 

@ForgeSubscribe

public void onBlockBreak(PlayerBreakBlockEvent ev) {

    System.out.println("Break!:" );

}

 

@Init

public void init(FMLInitializationEvent ev) {

 

MinecraftForge.EVENT_BUS.register(this);

}

 

Then I can see that the server does indeed go there but when I break a block I get no output from it, am I still missing something?

[epicsquare]

That's right, but you need to ensure FML is loading the coremod. Ninjar (for the coremods folder) coming soon

 

Oh you mean this? "Version 1.4.5-0: https://github.com/downloads/keepcalm/BlockBreak/blockbreak-1.4.5-0.jar for Minecraft 1.4.4 or 1.4.5, and MinecraftForge." (From your thread). I see. Are you planning on making a block place too? And what about if a block is broken by explosion?

 

Thanks

[xxxgamer]

Have you managed to register blocks getting destroyed?

[epicsquare]

Nope. I put that jar into coremods and now I get:

Again, not sure how to actually properly integrate that block break api. Kinda noob at this 

[xxxgamer]

That looks like you have 2 classes that have the same @mod name in then, They need to be unique.

[epicsquare]

Not my classes, its because of that jar in the coremods.

 

Game gives this error:

 

...

You have mod sources that are duplicate within your system

 

Mod Id : File name

 

BlockBreak : bin

BlockBreak : blockbreak-1.4.5-0.jar

 

Edit:

 

I removed the block break sources and added the jar as a reference. Now I get:

 

[sEVERE] [ForgeModLoader] Found a duplicate mod BlockBreak at [C:\...\Coding\mcp725\jars\coremods\blockbreak-1.4.5-0.jar, C:\....\Coding\mcp725\jars\coremods\blockbreak-1.4.5-0.jar]

 

What am I doing wrong? 

[xxxgamer]

Have you had any more luck getting an event registered?

[epicsquare]

Nope. I'm still stuck with that duplicate error. I have absolutely not the slightest of clues how to add API's to forge. And I can't find anything online either. I was hoping someone on these forums might help...

[keepcalm]

Ok, I updated and released my API (link in signature). To create events, have a class that extends Event and use MinecraftForge.EVENT_BUS.post(event) when you want to call it.
