[Getting Mod Ready for Release]

I just zip mine then rename it to .jar, easy.

[EntityLiving mounting the player]

Isn't there:

    	if (FMLCommonHandler.instance().getSide().isClient())

and

     	if (FMLCommonHandler.instance().getSide().isServer())

[Player Event Suggestions]

I've been trying to give a player some items on their first spawn in a world (singleplayer) and different items on respawn (multiplayer). I figured that if these events were added it would help a lot (It would also be good for triggering achievements, potion effects etc upon joining a custom world type). If you know how I can do this without these events i'd like to know, thanks.

 

 

PlayerSpawn Event - Triggered on first spawn in a world.

 

 

PlayerRespawn Event - Triggered on a player's respawn.

[Non-Living Entity Tracking Method: EntityRegistry.registerModEntity]

Hmm I'm not too sure about this white box problem but it seems to be a render issue. I had some problems getting my bullets to render when they extended EntityArrow/RenderArrow so I changed them to extend EntityThrowable/RenderThrowable which simplified a lot of things, especially textures. I can also suggest making sure in your EntityRocket class that the rocket spawn position is correct.

[[HELP] Rendering Problems with gun code]

You've made the entity but you haven't told it what to look like. I use:

RenderingRegistry.registerEntityRenderingHandler(EntityBullet.class, new RenderBullet());

My RenderBullet extends RenderSnowball and my EntityBullet extends EntityThrowable. Hope this helps

 

 

[Non-Living Entity Tracking Method: EntityRegistry.registerModEntity]

I'll show you how I did mine. This is probably the best way to use proxies. Note: Common proxy's DayZload method is empty. Hope this helps

 

 

The mod file:

      @SidedProxy(clientSide = "dayz.common.ClientProxy", serverSide = "dayz.common.CommonProxy")
    public static CommonProxy proxy;
     @Init
    public void DayZload(FMLInitializationEvent event)
    {
        EntityRegistry.registerModEntity(EntityBullet.class, "Bullet", 1, this, 250, 5, true);
         proxy.DayZload();
    }

ClientProxy:

 

@Override
   public void DayZload() 
   {
        RenderingRegistry.registerEntityRenderingHandler(EntityBullet.class, new RenderBullet());
   }

[How to make a GUI sidebar show while playing?]

I've never looked at Rei's code so it might be better then my way, but here is what I did:

 

First you need to set up your tick handler to also trigger on render ticks,

http://www.minecraftforge.net/wiki/Tutorials/Upgrading_To_Forge_for_1.3.1#Ticking

 

Don't open a gui screen, instead draw the elements you want during a render tick. (has to be during the  render tick or the images flicker)

Ahh okay. Thanks i'll look into it.

[How to make a GUI sidebar show while playing?]

I'm trying to make my Gui run on the side of the screen mid-game without becoming the main focus (much like how Rei's minimap is on screen but the mouse doesn't pop up and the player keeps moving). I've stopped the gui from pausing the game with doesGuiPauseGame() but it still stops the player moving and the mouse pops up. Does anyone have any ideas on how I would fix this?

[[Solved]Mod Not Working On Server - LoaderException]

Mmk so I rage quit from this for a few days and ended up figuring it out. Turns out I may be slightly retarded since I didn't read correctly how to do the @SidedProxy. I did find though that I had to put

@SidedProxy(clientSide = "net.minecraft.src.DayZ_ClientProxy", serverSide = "net.minecraft.src.DayZ_CommonProxy")

when I worked out of MCP. When I reobfuscated I changed it to

@SidedProxy(clientSide = "DayZ_ClientProxy", serverSide = "DayZ_CommonProxy")

so all good now thanks for the help.

 

 

[[Solved]Mod Not Working On Server - LoaderException]

I had a look at how IronChest does it and made some changes. The server starts now but nothing in the client proxy is rendered in either the client or the server. I also noticed that in  RenderingRegistry.instance().registerEntityRenderingHandler the .instance() comes out as deprecated.

You have hard references to client proxy.

Thats bad, take a look at SideProxy

 

 

D:

 

 

So to fix this I would put

 

 

 

@SidedProxy(clientSide = "net.minecraft.src.DayZ_ClientProxy", serverSide = "net.minecraft.src.DayZ_CommonProxy")

in the DayZ_Base file?

So is there any chance of this being implemented?

[Where to place my .javas in 1.3.1(Please help with a new problem!)]

• Biome, worldgen, item, block etc (files that go in both client and server) go in the common folder.
  
• render, gui, model (client only) files go in the client section.
  
• server files go in the server section.
  If you're not sure check where the vanilla minecraft ones are.

Ahh I kinda see now, thanks. Forge would help a lot if it changed it from private to protected when it patched it (hint hint).
