[Solved] Changeing custom rendered item model depending on what 'mode' it's in

[chimera27]

I'm trying to make an item that is 3D rendered, but changes it's model depending on what 'mode' the player is in, where mode is a int in the item's file that changes how the item behaves. I have a custom renderer working, and have the item's 'mode' feature working, but have run into a roadblock in getting the custom renderer to render the right mode. The problem is, to be accessible by the renderer class, the variable 'mode' has to be static, but for the mode to be able to be changed in game, it can't be static!! I'm probs just being a stupid java noob and the answer is likely obvious to more seasoned modders, but I can't see a good way around it other than making a new item for each 'mode' and having a tick handler switch what item it is on button press (which get's VERY cumbersome and broken seeing as there are a number of upgrades for each mode, all of which are accounted for in the item file as is, but would ALL require they're own item file if I were to do this). I have been able to change the item's icon based on mode, and would assume there would be SOME way to change it's model aswell. I'll post my item and renderer file below, as well as anything else anyone asks me to put up, but I can't figure out a good solution for this! Any advice would be greatly appreciated!!

Hi

 

The answer is "it depends on what you want".

If you want all ItemBeams in the game to render exactly the same, so when you change one mode you change them all, then you could use the static variable you currently have.

If you want different ItemBeams to have different modes eg the player can have two ItemBeams in different modes in their hotbar at the same time, then you will need to store that information somewhere else - often this can be the item damage (if this isn't needed for tool usage) - for example like ItemCloth, or a non-static member variable (like in ItemSword).  You have access to this through the ItemStack that the renderer receives.

The problem is that I can only change what 3D model to use by making that variable static, and I can't switch modes in game with the variable being static... which defies the point having it use different models because the mode can't be changed! Even if I did use the damage I wouldn't be able to access that from RenderBeam because it isn't static

Hi

 

I'll send you a PM to discuss further...

DEEEEEEEERRRRRRRRPPPPPPP nevermind I thought there was some strange bug making it not able to change when that was static, turns out it was working right the whole time....
