I am porting LanteaCraft to 1.12, and i cant figure out how to change everything that uses Tesselate to using BufferBuilder
here is one method (it contains most of the stuff i dont know how to port):
private void renderItemIn2D(Tessellator t, float u1, float v0, float u0, float v1, int w, int h, float p_78439_7_) {
t.startDrawingQuads();
t.setNormal(0.0F, 0.0F, 1.0F);
t.addVertexWithUV(0.0D, 0.0D, 0.0D, (double) u1, (double) v1);
t.addVertexWithUV(1.0D, 0.0D, 0.0D, (double) u0, (double) v1);
t.addVertexWithUV(1.0D, 1.0D, 0.0D, (double) u0, (double) v0);
t.addVertexWithUV(0.0D, 1.0D, 0.0D, (double) u1, (double) v0);
t.draw();
t.startDrawingQuads();
t.setNormal(0.0F, 0.0F, -1.0F);
t.addVertexWithUV(0.0D, 1.0D, (double) (0.0F - p_78439_7_), (double) u1, (double) v0);
t.addVertexWithUV(1.0D, 1.0D, (double) (0.0F - p_78439_7_), (double) u0, (double) v0);
t.addVertexWithUV(1.0D, 0.0D, (double) (0.0F - p_78439_7_), (double) u0, (double) v1);
t.addVertexWithUV(0.0D, 0.0D, (double) (0.0F - p_78439_7_), (double) u1, (double) v1);
t.draw();
float f5 = 0.5F * (u1 - u0) / (float) w;
float f6 = 0.5F * (v1 - v0) / (float) h;
t.startDrawingQuads();
t.setNormal(-1.0F, 0.0F, 0.0F);
int k;
float f7;
float f8;
for (k = 0; k < w; ++k) {
f7 = (float) k / (float) w;
f8 = u1 + (u0 - u1) * f7 - f5;
t.addVertexWithUV((double) f7, 0.0D, (double) (0.0F - p_78439_7_), (double) f8, (double) v1);
t.addVertexWithUV((double) f7, 0.0D, 0.0D, (double) f8, (double) v1);
t.addVertexWithUV((double) f7, 1.0D, 0.0D, (double) f8, (double) v0);
t.addVertexWithUV((double) f7, 1.0D, (double) (0.0F - p_78439_7_), (double) f8, (double) v0);
}
t.draw();
t.startDrawingQuads();
t.setNormal(1.0F, 0.0F, 0.0F);
float f9;
for (k = 0; k < w; ++k) {
f7 = (float) k / (float) w;
f8 = u1 + (u0 - u1) * f7 - f5;
f9 = f7 + 1.0F / (float) w;
t.addVertexWithUV((double) f9, 1.0D, (double) (0.0F - p_78439_7_), (double) f8, (double) v0);
t.addVertexWithUV((double) f9, 1.0D, 0.0D, (double) f8, (double) v0);
t.addVertexWithUV((double) f9, 0.0D, 0.0D, (double) f8, (double) v1);
t.addVertexWithUV((double) f9, 0.0D, (double) (0.0F - p_78439_7_), (double) f8, (double) v1);
}
t.draw();
t.startDrawingQuads();
t.setNormal(0.0F, 1.0F, 0.0F);
for (k = 0; k < h; ++k) {
f7 = (float) k / (float) h;
f8 = v1 + (v0 - v1) * f7 - f6;
f9 = f7 + 1.0F / (float) h;
t.addVertexWithUV(0.0D, (double) f9, 0.0D, (double) u1, (double) f8);
t.addVertexWithUV(1.0D, (double) f9, 0.0D, (double) u0, (double) f8);
t.addVertexWithUV(1.0D, (double) f9, (double) (0.0F - p_78439_7_), (double) u0, (double) f8);
t.addVertexWithUV(0.0D, (double) f9, (double) (0.0F - p_78439_7_), (double) u1, (double) f8);
}
t.draw();
t.startDrawingQuads();
t.setNormal(0.0F, -1.0F, 0.0F);
for (k = 0; k < h; ++k) {
f7 = (float) k / (float) h;
f8 = v1 + (v0 - v1) * f7 - f6;
t.addVertexWithUV(1.0D, (double) f7, 0.0D, (double) u0, (double) f8);
t.addVertexWithUV(0.0D, (double) f7, 0.0D, (double) u1, (double) f8);
t.addVertexWithUV(0.0D, (double) f7, (double) (0.0F - p_78439_7_), (double) u1, (double) f8);
t.addVertexWithUV(1.0D, (double) f7, (double) (0.0F - p_78439_7_), (double) u0, (double) f8);
}
t.draw();
}
and here is another one:
public void renderDefaultInventoryBlock(Block block, int metadata, Trans3 trans, BlockModelRenderer rb) {
setUpTextureOverride(rb);
setColorMultiplier(0xffffff);
Tessellator tess = Tessellator.getInstance();
BufferBuilder buff = tess.getBuffer();
buff.setColorOpaque_F(1, 1, 1);
buff.begin(7, DefaultVertexFormats.BLOCK);
GL11.glTranslatef(0.0f, -0.1f, 0.0f);
renderCube(buff, trans, null, block, 0, 0, 0, metadata, 0xf000f0);
tess.draw();
}
im thanking anyone in advance for helping me
