Thanatos_0173_2

I need help for modding in 1.16. Do someone know a site where I can get help ?

I don't think so. Here is the code: package com.thanatos.magicalgems.screen; import com.thanatos.magicalgems.main; import com.mojang.blaze3d.matrix.MatrixStack; import com.mojang.blaze3d.systems.RenderSystem; import com.thanatos.magicalgems.container.LightningChannelerContainer; import net.minecraft.client.gui.screen.inventory.ContainerScreen; import net.minecraft.entity.player.PlayerInventory; import net.minecraft.util.ResourceLocation; import net.minecraft.util.text.ITextComponent; public class LightningChannelerScreen extends ContainerScreen<LightningChannelerContainer> { private final ResourceLocation GUI = new ResourceLocation(main.MODID, "textures/gui/lightning_channeler_gui.png"); public LightningChannelerScreen(LightningChannelerContainer screenContainer, PlayerInventory inv, ITextComponent titleIn) { super(screenContainer, inv, titleIn); } @Override public void render(MatrixStack matrixStack, int mouseX, int mouseY, float partialTicks) { this.renderBackground(matrixStack); super.render(matrixStack, mouseX, mouseY, partialTicks); this.renderHoveredTooltip(matrixStack, mouseX, mouseY); } @Override protected void drawGuiContainerBackgroundLayer(MatrixStack matrixStack, float partialTicks, int x, int y) { RenderSystem.color4f(1f, 1f, 1f, 1f); this.minecraft.getTextureManager().bindTexture(GUI); int i = this.guiLeft; int j = this.guiTop; this.blit(matrixStack, i, j, 0, 0, this.xSize, this.ySize); if(container.isLightningStorm()) { this.blit(matrixStack, i + 82, j + 9, 176, 0, 13, 17); } } }

First, let me tell you that I know I'm not the only one posting about this error, but I haven't found anything with my specific error. So, I've created a GUI (well I've actually copy-paste it but don't say it to anyone : - ) ), and I wanted to add a new slot. I've changed the value TE_INVENTORY_SLOT_COUNT from 2 to 3, but I kept on havving the error. Can someone help me?
