[1.5.2] adding custom ingamegui with item right click


happyPenguin

Recommended Posts

Hi im just wondering if it's possible to add my own in-game gui without editing the ingamegui.class,

 

My plan is similar to the pumpkin how it adds a pumpkin gui shadow when added the helmet slot.

 

or has anyone got a different idea of doing this but with the same output?

Short answer:

Yes

 

Long answer:

You need at least three classes to do it.

 

The item or block itself

Packet Handler implements IPacketHandler

Gui Renderer  implements ITickHandler

 

These two lines in your base Init function:

overlayGui = new MyGUIrenderer();
TickRegistry.registerTickHandler(overlayGui, Side.CLIENT);

 

And this will get you drawing something like the pumpkin head.  Actually, 95% of this is the pumpkin head.

 

            	u = 32;
                float minU = (float)u/512; //my texture was 512x512
                float minV = 0;
                float maxU = (float)(u+32)/512;
                float maxV = 0.0625F;
            	ScaledResolution scaledresolution = new ScaledResolution(this.mc.gameSettings, this.mc.displayWidth, this.mc.displayHeight);
                int k = scaledresolution.getScaledWidth();
                int l = scaledresolution.getScaledHeight();
                GL11.glDisable(GL11.GL_DEPTH_TEST);
                GL11.glDepthMask(false);
                GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
                GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
                GL11.glDisable(GL11.GL_ALPHA_TEST);
                this.mc.renderEngine.bindTexture("/mods/MyMod/textures/gui/gui.png");
                Tessellator tessellator = Tessellator.instance;
                tessellator.startDrawingQuads();
                tessellator.addVertexWithUV(0.0D,      (double)l, -90.0D, minU, maxV);
                tessellator.addVertexWithUV((double)k, (double)l, -90.0D, maxU, maxV);
                tessellator.addVertexWithUV((double)k, 0.0D,      -90.0D, maxU, minV);
                tessellator.addVertexWithUV(0.0D,      0.0D,      -90.0D, minU, minV);
                tessellator.draw();
                GL11.glDepthMask(true);
                GL11.glEnable(GL11.GL_DEPTH_TEST);
                GL11.glEnable(GL11.GL_ALPHA_TEST);
                GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);

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.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

    • I have a problem, I am trying to put two different effects to two different armors but when I run it only the emerald armor effect works. This is the code public class ModArmorItem extends ArmorItem{ private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.OBSIDIAN, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); public ModArmorItem(ArmorMaterial pMaterial, Type pType, Properties pProperties) { super(pMaterial, pType, pProperties); } @Override public void onArmorTick(ItemStack stack, Level world, Player player){ if (!world.isClientSide()) { if (hasFullSuitOfArmorOn(player)) { evaluateArmorEffects(player); } } } private void evaluateArmorEffects(Player player) { for (Map.Entry<ArmorMaterial,MobEffectInstance> entry : MATERIAL_TO_EFFECT_MAP.entrySet()){ ArmorMaterial mapArmorMaterial = entry.getKey(); MobEffectInstance mapStatusEffect = entry.getValue(); if (hasCorrectArmorOn(mapArmorMaterial, player)) { addStatusEffectForMaterial(player, mapArmorMaterial, mapStatusEffect); } } } private void addStatusEffectForMaterial(Player player, ArmorMaterial mapArmorMaterial, MobEffectInstance mapStatusEffect) { boolean hasPlayerEffect = player.hasEffect(mapStatusEffect.getEffect()); if (hasCorrectArmorOn(mapArmorMaterial, player) && !hasPlayerEffect) { player.addEffect(new MobEffectInstance(mapStatusEffect)); } } private boolean hasCorrectArmorOn(ArmorMaterial material, Player player) { for (ItemStack armorStack : player.getInventory().armor){ if (!(armorStack.getItem() instanceof ArmorItem)) { return false; } } ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem()); ArmorItem breastplace = ((ArmorItem)player.getInventory().getArmor(2).getItem()); ArmorItem leggins = ((ArmorItem)player.getInventory().getArmor(1).getItem()); ArmorItem boots = ((ArmorItem)player.getInventory().getArmor(0).getItem()); return helmet.getMaterial() == material && breastplace.getMaterial() == material && leggins.getMaterial() == material && boots.getMaterial() == material; } private boolean hasFullSuitOfArmorOn(Player player){ ItemStack helmet = player.getInventory().getArmor(3); ItemStack breastplace = player.getInventory().getArmor(2); ItemStack leggins = player.getInventory().getArmor(1); ItemStack boots = player.getInventory().getArmor(0); return !helmet.isEmpty() && !breastplace.isEmpty() && !leggins.isEmpty() && !boots.isEmpty(); } } Also when I place two effects on the same armor, the game crashes. Here is the crash file. The code is the same, only this part is different   private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); I hope you guys can help me. Thanks.
