Here is my code for the particules.

 

 

 

package ThelosMod.Particules;

 

import net.minecraft.client.Minecraft;

import net.minecraft.client.particle.EntityFX;

import net.minecraft.client.renderer.Tessellator;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.util.AxisAlignedBB;

import net.minecraft.util.ResourceLocation;

import net.minecraft.world.World;

import static org.lwjgl.opengl.GL11.*;

 

import org.lwjgl.opengl.GL11;

 

import ThelosMod.ThelosMod;

 

public class ThelosParticlesFX extends EntityFX

{

 

private static final ResourceLocation texture = new ResourceLocation("thelosmod","textures/particles/thelos.png");

 

public ThelosParticlesFX(World world, double x,double y, double z)

{

super(world, x, y, z);

setGravity(0.0F);

 

}

 

public void renderParticle(Tessellator tess,float partialTicks, float par3, float par4, float par5,float par6, float par7)

{

Minecraft.getMinecraft().renderEngine.bindTexture(texture);

GL11.glDisable(GL11.GL_LIGHTING);

glDepthMask(false);

glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

glAlphaFunc(GL_GREATER,0.003921569F);

tess.startDrawingQuads();

tess.setBrightness(getBrightnessForRender(partialTicks));

float scale= 0.1F * particleScale;

float x = (float)(prevPosX + (posX - prevPosX) * partialTicks - interpPosX);

float y = (float)(prevPosY + (posX - prevPosY) * partialTicks - interpPosY);

float z = (float)(prevPosZ + (posX - prevPosZ) * partialTicks - interpPosZ);

tess.addVertexWithUV(x - par3 * scale - par6 * scale, y- par4* scale ,z - par5*scale - par7 * scale, 0, 0);

tess.addVertexWithUV(x - par3 * scale + par6 * scale, y+ par4* scale ,z - par5*scale + par7 * scale, 1, 0);

tess.addVertexWithUV(x + par3 * scale + par6 * scale, y+ par4* scale ,z + par5*scale + par7 * scale, 1, 1);

tess.addVertexWithUV(x + par3 * scale - par6 * scale, y- par4* scale ,z + par5*scale - par7 * scale, 0, 1);

tess.draw();

glDisable(GL_BLEND);

glDepthMask(true);

glAlphaFunc(GL_GREATER, 0.1F);

}

 

 

public int getFXLayer()

{

return 3;

}

 

public ThelosParticlesFX setMaxAge(int maxAge)

{

particleMaxAge=maxAge;

return this;

}

public ThelosParticlesFX setGravity(float gravity)

{

particleGravity=gravity;

return this;

}

public ThelosParticlesFX setScale(float scale)

{

particleScale=scale;

return this;

}

}

 

 

 

I don't know what the problem is and i Follow this tut0 to see how it works :

 

I don't understand why my particles don't stay 3 blocks on top of the head of the player ! Is so strange, and even if i do nothing in the method OnUpdate(), particles are going away anyway. Modify the gravity doesn't change anything too.

 

 

Thanks for your futur answer

 

No idea ?
