RenderItem

[Asonyx]

Pour initialiser la variable itemRender (de type RenderItem), tu doit utiliser la methode getRenderItem() de Minecraft :

Minecraft.getMinecraft().getRenderItem()

Pour ta class RenderDyna, essaye de mettre ce code :
(En remplaçant RenderItemThrowable par RenderDyna)

@SideOnly(Side.CLIENT)
public class RenderItemThrowable<T extends Entity> extends Render<T> {

    protected final Item item;
    private final RenderItem itemRenderer;

    public RenderItemThrowable(RenderManager renderManagerIn, Item itemIn, RenderItem itemRendererIn) {
        super(renderManagerIn);
        this.item = itemIn;
        this.itemRenderer = itemRendererIn;
    }
    public void doRender(T entity, double x, double y, double z, float entityYaw, float partialTicks) {
        GlStateManager.pushMatrix();
        GlStateManager.translate((float)x, (float)y, (float)z);
        GlStateManager.enableRescaleNormal();
        GlStateManager.rotate(-this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
        GlStateManager.rotate((float)(this.renderManager.options.thirdPersonView == 2 ? -1 : 1) * this.renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
        GlStateManager.rotate(180.0F, 0.0F, 1.0F, 0.0F);
        this.bindTexture(TextureMap.LOCATION_BLOCKS_TEXTURE);

        if (this.renderOutlines)
        {
            GlStateManager.enableColorMaterial();
            GlStateManager.enableOutlineMode(this.getTeamColor(entity));
        }

        this.itemRenderer.renderItem(this.getStackToRender(entity), ItemCameraTransforms.TransformType.GROUND);

        if (this.renderOutlines)
        {
            GlStateManager.disableOutlineMode();
            GlStateManager.disableColorMaterial();
        }

        GlStateManager.disableRescaleNormal();
        GlStateManager.popMatrix();
        super.doRender(entity, x, y, z, entityYaw, partialTicks);
    }

    public ItemStack getStackToRender(T entityIn)
    {
        return new ItemStack(this.item);
    }

    @Nullable
    protected ResourceLocation getEntityTexture(Entity entity) {
        return TextureMap.LOCATION_BLOCKS_TEXTURE;
    }
}

Et au passage, si tu peut envoyer la class ou tu a engregistrer l’entity de ta dynamite.

[Drastic]

@Asonyx Merci mais toujour le mm bug…

Voici la classe ou j’enregistre mes Entités.

public class EntityInit
{
    public static void registerEntities()
    {
        registerEntity("dyna", EntityDyna.class, Reference.ENTITY_DYNA, 50, 11437146, 000000);
    }
    
    private static void registerEntity(String name, Class<? extends Entity> entity, int id, int range, int color1, int color2)
    {
        EntityRegistry.registerModEntity(new ResourceLocation(Reference.MODID + ":" + name), entity, name, id, Main.instance, range, 1, true, color1, color2);
    }
}

[Asonyx]

Juste, est-ce que c’est toujour le même crash ?

Essaye de remplacer dans la class RenderDyna la fonction getEntityTexure par ça :

    @Nullable
    protected ResourceLocation getEntityTexture(Entity entity) throws NullPointerException {
        return TextureMap.LOCATION_BLOCKS_TEXTURE;
    }

[Drastic]

@Asonyx a dit dans RenderItem :

                                                                                                                                @Nullable                                                                                                                                                                                protected ResourceLocation getEntityTexture(Entity entity) throws NullPointerException {                                                                                                                                                                                    return TextureMap.LOCATION_BLOCKS_TEXTURE;                                                                                                                                                                                }

[Asonyx]

Les entitées doivent être dans la méthode init, alors que tu l’as mis dans preInit

[Drastic]

@Asonyx ah ok

[Drastic]

@Asonyx re, désolé de te redéranger ,mais, je voudrais que l’entité n’explose que si elle atterrit sur un bloc. Comment faire ?
Merci

[Asonyx]

Normalement, dans onImpact, tu peut utiliser une fonction qui s’appelle je crois isOnGround() qui retourne un boolean (je ne suis pas sûr)
Ou une fontion de result

[Drastic]

@Asonyx yas inGround et onGround mais aucun ne va.

[Asonyx]

Sinon tu vérifie si l’entité touchée est null

[Drastic]

@Asonyx Comment ca ?
