When I aim at the ground and shoot the gun I made, a large rectangle, the same color as the entity (bullet) just flashes in front of my view.

In third person I can see it's roughly 4 blocks wide and 3 high. Completely flat. How can I fix this?

you would have to 1 change the entity size and 2 make a renderer (like i said earlier). EntityThrowable will always be rendered in a way that will make them look like the image is facing the player, if you want to have more realistic bullet you're gonna have to make a class extends Render and register it in your client proxy

I've already made a render class for the bullet. It works fine and looks like I want it to. When I shoot it fires and does damage and interacts with mobs. I've registered it in the proxy. But when I look down and shoot the white rectangle flashes.

<troll> pic or it didnt happen </troll>

 

no no just kidding, but srly can we have some pic / video so we can understand whats going on

 

because since you are usign a renderer, the problem can now be anything, maybe its you graphic card, maybe your opengl 1 setting are in an odd state causing this effect etc etc

It seems to appear on random living entities. But only one at a time. And how do I use this insert image thing? lol

It seems to appear on random living entities

It : the visual problem ?  as like, randomly cows will start flickering/changing color or wtv is it that your visual bug do ?

I have a picture but I don't get how to use the insert image.

use imagebin or wtv

damn, can you show us the render code ?

ok, well 2 things, either this code is copy pasted, either you name your variable in very weird ways (f1, f2, f3, f4, f5, f6) in either case im not suuure exactly where the problem is because im not sure hat youre trying to do but honestly by looking at the code it seems that the picture is doign EXACTLY what you asked it to do...

 

tessellator.addVertex(-8.0D, -2.0D, 0.0D);
		tessellator.addVertex(8.0D, -2.0D, 0.0D);
		tessellator.addVertex(8.0D, 2.0D, 0.0D);
		tessellator.addVertex(-8.0D, 2.0D, 0.0D);

^ this is a pretty big rectangle actually

 

GL11.glDisable(GL11.GL_TEXTURE_2D);
	GL11.glDisable(GL11.GL_LIGHTING);
	GL11.glEnable(GL11.GL_BLEND);

 

^ blending is enabled so you expect your bolt to be transparent, texture2D are DISABLED, so no image on your bullets and lighting disabled... result may vary since its LWJGL and opengl1

 

i would try to play with glEnable/glDisable those 3 thing above.

other then that, if you want to play if safe, remove a MAX ammount of code and add little by little

 

and hum ..... if you dont know what the code is doing ... try understanding first ... usually copy paste dont get prople very far ..... sorry if its mean :\

I was rushing so I didn't bother looking it over but thanks and no it's not mean lol.
