So I found a way to work around the already-terrible attribute system using reflection and player capabilities. Using this, I was able to modify player speed quite nicely, and it worked, and using ObfuscationReflectionHelper I made it so it SHOULD work in normal minecraft. However, it does not :/.

My code

        PlayerCapabilities cap = player.capabilities;
float speed = cap.getWalkSpeed();
speed *=1.5;
ObfuscationReflectionHelper.setPrivateValue(PlayerCapabilities.class, cap, speed ,"walkSpeed","field_73357_f");

 

walkSpeed is a private value in playercapabilities, and I got the field_73357_f from fields.csv in /mcp/conf

 

Help appreciated :)

 

Thanks.

1. When modifying speed, it modifies your players field of view, which can get annoying...

2. I've only gotten it to work in a very crude way, that glitches up, and could cause incompatibilities with other mods.

 

Aside from that, Can anyone help me with my issue? :l

      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.

      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
