(in intellij IDEA)i've tested out the "gradlew build" in non build areas and it worked fine. but when i did it in the project it told me "Error occurred during initialization of VM Could not reserve enough space for 3145728KB object heap". what gives?

This means you have a 32-Bit JDK, you should uninstall it and get a 64-Bit JDK

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

I recommend specifying "org.gradle.java.home = C: / Program Files / Java / jdk1.8.0_241" in gradle.properties

specify the path to 64 bit jdk (NOT Program Files (x86)/Java , it's 32 bit)

this is what my gradle.properties file says

  

# Sets default memory used for gradle commands. Can be overridden by user or command line properties.
# This is required to provide enough memory for the Minecraft decompilation process.
org.gradle.jvmargs=-Xmx3G
org.gradle.daemon=false

org.gradle.jvmargs=-Xmx3G - Java can use a maximum of 3 GB of RAM.

org.gradle.jvmargs=-Xms3G - Java can use a minimum of 3 GB of RAM.

org.gradle.jvmargs=-Xms512m -Xmx4G  - Java can use a minimum of 512MB and maximum of 4GB of RAM.

org.gradle.java.home=C:/Program Files/Java/jdk1.8.0_241 - Gradle uses that version of Java which is in this folder.

org.gradle.java.home=C:/Program Files (x86)/Java/jdk1.8.0_241 - This installs the 32 bit version of Java (in Program Files (x86)).

#org.gradle.java.home=/usr/java/jdk1.8.0_241 - I use this line when Linux is running.

You need to download jdk 8 64 bit from here and install it. Then here (C:/Program Files/Java/) you will have this folder jdk1.8.0_241. Now we just need to add this line to the properties file.

If there are problems, try to allocate more RAM.

      How to apply shader to a openGL render object 1.12.2

      By Sultan · Posted

      Hey guys, i'm currently developping a mod with forge 1.12.2 2860 and i'm using optifine and gradle 4.9. The thing is i'm trying to figure out how to show the player's body in first person. So far everything's going well since i've try to use a shader. The player's body started to blink dark when using a shader. I've try a lot of shader like chocapic, zeus etc etc but still the same issue. So my question is : How should i apply the current shader to the body ? At the same time i'm also drawing a HUD so maybe it could be the problem?   Here is the issue :    And here is the code where i'm trying to display the body :    private static void renderFirstPersonBody(EntityPlayerSP player, float partialTicks) { Minecraft mc = Minecraft.getMinecraft(); GlStateManager.pushMatrix(); GlStateManager.pushAttrib(); try { // Préparation OpenGL GlStateManager.enableDepth(); GlStateManager.depthMask(true); GlStateManager.enableAlpha(); GlStateManager.alphaFunc(GL11.GL_GREATER, 0.1F); GlStateManager.enableBlend(); GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA); // Éclairage correct pour shaders GlStateManager.enableLighting(); RenderHelper.enableStandardItemLighting(); GlStateManager.enableRescaleNormal(); // Active la lightmap pour les shaders mc.entityRenderer.enableLightmap(); // Position de rendu interpolée double px = player.lastTickPosX + (player.posX - player.lastTickPosX) * partialTicks; double py = player.lastTickPosY + (player.posY - player.lastTickPosY) * partialTicks; double pz = player.lastTickPosZ + (player.posZ - player.lastTickPosZ) * partialTicks; GlStateManager.translate( px - mc.getRenderManager().viewerPosX, py - mc.getRenderManager().viewerPosY, pz - mc.getRenderManager().viewerPosZ ); // Rendu du joueur sans la tête Render<?> render = mc.getRenderManager().getEntityRenderObject(player); if (render instanceof RenderPlayer) { RenderPlayer renderPlayer = (RenderPlayer) render; boolean oldHeadHidden = renderPlayer.getMainModel().bipedHead.isHidden; boolean oldHeadwearHidden = renderPlayer.getMainModel().bipedHeadwear.isHidden; renderPlayer.getMainModel().bipedHead.isHidden = true; renderPlayer.getMainModel().bipedHeadwear.isHidden = true; setArmorHeadVisibility(renderPlayer, false); renderPlayer.doRender(player, 0, 0, 0, player.rotationYaw, partialTicks); renderPlayer.getMainModel().bipedHead.isHidden = oldHeadHidden; renderPlayer.getMainModel().bipedHeadwear.isHidden = oldHeadwearHidden; setArmorHeadVisibility(renderPlayer, !oldHeadwearHidden); } // Nettoyage post rendu mc.entityRenderer.disableLightmap(); GlStateManager.disableRescaleNormal(); } catch (Exception e) { // silent fail } finally { GlStateManager.popAttrib(); GlStateManager.popMatrix(); } }   Ty for your help.

      By TileEntity · Posted

      Keep on using the original Launcher Run Vanilla 1.12.2 once and close the game Download Optifine and run optifine as installer (click on the optifine jar) Start the launcher and make sure the Optifine profile is selected - then test it again

      How Can I Safely Play an Old Version of Minecraft?

      By amelia2132 · Posted

      Hi everyone, I’m hoping to revisit an old version of Minecraft — specifically around Beta 1.7.3 — for nostalgia’s sake. I’ve heard you can do this through the official Minecraft Launcher, but I’m unsure how to do it safely without affecting my current installation or save files. Are there any compatibility issues I should watch out for when switching between versions? Would really appreciate any tips or advice from anyone who’s done this before! – Adam
