Rendering arrow like item

[endershadow]

I want to render my arrow like item, but I can't get it to work correctly. I've tried the arrow renderer and the snowball renderer. but so far I've had no luck. please help.

[Raggarcowboy]

In what way does it not work? You mean you can't see the arrow? I just got a whole lot of help to render a throwable item and therefore I know that there's a craptonne of stuff that could be wrong. If it's not private, it would also help if you posted your source code!

i have an entity arrow that works all crrectly but i dont know how to get it to look like what i want, it allways looks like the missing texture

if you can help me fix this i can help this guy by posting the code for it.

 

this part methinks

 

this.loadTexture("/item/arrows.png");

Just use the arrows.png as a template to make your own arrow and then you replace "/item/arrows.png" with "/relative/path/to/your/arrowstexture.png", the code is counting from the render class so if the texture is in the middle of all your mod's classes, the path would just be "/arrowtexture.png" and if it is in a folder it would be "/foldername/arrowtexture.png". Get it? Try that

okay i got it to work, so endershadow you need alot of classes to make one rendered throwable or shootable entity, you need a render class, an entity class and a item class, and you need to register the item entity and renderer in your main mod class then the entity and the rederer again in your client proxy, i wil ommit the basic item code in the main mode class as i presume you can do that part.

P.S this is an example dagger.

Main mod class (omitting basic item code)

@Init
proxy.registerRenderers();
	EntityRegistry.registerModEntity(EntityRockSnowball.class, "RockSnowball", 2, this , 250, 1, false);

It just doesn't show up. and I tried copying the arrow render class and changing the string and the entity it referenced, but it didn't work.

[ashtonr12]

did you do the things above?

try copy pasting some of my code to double check?

double check the referanced classes ie everytime renderdagger is metioned make sure it is spelt correctly and such

i know the above works as i am using it so you must be missing something somewhere what a said a min ago and if that doesnt work post your code and will take a look

Could you post source code? I might not be able to respond till tomorrow but I'll see then

[endershadow]

here's a link to my renderer on github. this one is based off the snowball renderer.

[ashtonr12]

if you want it to look like an arrow what good is it using the snowball renderer?

[endershadow]

Because some of them need to look like a snowball.

I hardly doubt this is the problem since the arrow isn't rendering but you might always check at least, replace this.loadTexture("/mods/lyoko/textures/items/laserarrow.png") with this.loadTexture("/textures/items/laserarrow.png") since it counts the texture path relative to the render code.

[ashtonr12]

its not that its a coding problem as if it were that then the render would come up as missing texture while in flight.

why dont you just use the code i provided you with? since we know that works.

[endershadow]

but that's just it, I used what you used and it gave me the same problem. invisible entities. Could it be that the entities are too fast?
