Rendering an Image into the world[Solved]

[Lua]

Wait isnt the problem in here

public static void drawTexturedQuadFit(double x, double y, double width, double height, double zLevel)
{
	caveman = caveman.getCaveman();
	Tessellator tessellator = Tessellator.instance;
	if(caveman != null)
	{
		for(int i = 0; i < caveman.func_110138_aP(); i++)
		{
			if(caveman.func_110138_aP() > i)
			{
				tessellator.startDrawingQuads();
				tessellator.setColorOpaque(0, 255, 0);
				tessellator.addVertexWithUV(x + 0, y + height, zLevel, 0, 1);
				tessellator.addVertexWithUV(x + width, y + height, zLevel, 1, 1);
				tessellator.addVertexWithUV(x + width, y + 0, zLevel, 1, 0);
				tessellator.addVertexWithUV(x + 0, y + 0, zLevel, 0, 0);
				tessellator.setColorOpaque(0, 255, 0);
				tessellator.draw();
			}
			else
			{
				tessellator.startDrawingQuads();
				tessellator.setColorOpaque(255, 0, 0);
				tessellator.addVertexWithUV(x + 0, y + height, zLevel, 0, 1);
				tessellator.addVertexWithUV(x + width, y + height, zLevel, 1, 1);
				tessellator.addVertexWithUV(x + width, y + 0, zLevel, 1, 0);
				tessellator.addVertexWithUV(x + 0, y + 0, zLevel, 0, 0);
				tessellator.setColorOpaque(255, 0, 0);
				tessellator.draw();
			}
		}
	}
}

 

Because before I added that it was working

[hydroflame]

give me another maybe 10 minute ive hacked one togheter ill give it to you

heres a health bar rendere i hacked in ~10 minute, artefact free

just register it and you're good to go

[Lua]

float interp = timer.renderPartialTicks;

Got an npe at ^

[hydroflame]

right, i made special change to the Minecraft class

 

change it to

 

float interp = 1;

 

for now, ill make the proper code later

[Lua]

Wut, I cant edit base classes...

i know, change it to float interp = 1; instead

[Lua]

http://gyazo.com/13704bfdbee6eac630adde08953337ce This is what happens

[Lua]

Like when he takes damage the other bar starts to happen

[hydroflame]

have you copied the entire class ?

this is what it looks like for me:

http://imagebin.org/267029

[Lua]

is it my texture?

http://gyazo.com/4c72117aef825f9dbcaa98c2e1db6ce9

 

Heres my code. but yeah I think I copied everything:

	private Timer timer;

public void HealthBarRenderer()
{
	Field[] fields = Minecraft.getMinecraft().getClass().getDeclaredFields();
	for(Field field : fields)
	{
		if(field.getType().isAssignableFrom(Timer.class))
		{
			field.setAccessible(true);
			try

				timer = (Timer) field.get(Minecraft.getMinecraft());
			}
			catch(IllegalArgumentException e)
			{
				e.printStackTrace();
			}
			catch(IllegalAccessException e)
			{
				e.printStackTrace();
			}
		}

  Quote

public void HealthBarRenderer()

originally was

  Quote

public HealthBarRenderer()

meaning its the constructor

 

this constructor was suppose to set the timer to somethign so that shit renders well

 

please copy the WHOLE class and register it

[Lua]

Okay I changed it to a new class and registered it and stuff but  yeah its my texture what is messing it up, cant I have http://gyazo.com/4c72117aef825f9dbcaa98c2e1db6ce9 this because id like it to have a border

[hydroflame]

to future reader, this is the final version of my health displayer, feel free to use it and change ForgeRevCommonProxy.blankTexture to a white texture 1x1

artefact free

you can also change the healthLength and healthHeight if you wish

 

 

well start by usign a white 1x1 texture, after that adding a border wouldn't be hard (and you can always surround everythign with a if(entity instanceof Caveman) if you dotn want to render the other entities the same way

[Lua]

Okay, thanks for everything:D
