[Un-solved] How are blocks rendered

[Zealock]

Hey, i'm looking for a way to modify blocks being rendered on a client.

 

For instance i want to make certain blocks become invisible until someone gets close, a good example of what i'm trying to do is to place a barrier on the ground and change your held item to something else until the barrier on the ground goes invisible, thats what i'm going for.

 

A few things have crossed my mind and one was using a core mod and modify the BlockBarrier.class and override the (getRenderType()) method to return a variable for dynamic modification (like when a player gets close i can set it to either 3 or -1). (i believe -1 ignores rendering, 3 renders like a normal block please confirm this  ) 

 

Whats the best way to achieve this? I'm currently using minecraft forge 1.8.9

Going to use TESR to achieve my goal, thanks all :)

Even if you have other ideas on modifying vanilla blocks rendering, but don't know how the rendering works, id still like to see your feedback

This is a horrible idea. Bad modder, no cookie.  Core mods are not allowed here.

 

I suspect the easiest way to do what you want to do will be to use a TESR, although I don't know if it would be possible using a FastTESR, but if so, that would be better.

You might have missed a pillar of Forge ideology: simply extend the class, override what methods you want to change, and use this new class...

You don't HAVE to use Barrier blocks, you WANT to use something that works like Barrier blocks.
ASM is incredibly bad if you don't know what you are doing, and as time and time again has been proven by countless users in the MC modding community, unless you have a few years of expertise, chances are that you do not.
In fact, countless core-mods could do what was stated above, and look at that, no ASM needed at all.
 

To make something go invisible, a FastTESR could be used. Override getMaxRenderDistanceSquared in the TE to return the cutoff-point for (rendering->not-rendering)². Default is 4096 (64 block / 4 chunks distance)

Simple, yet effective way of turning invisible, with minimal code required.

Got it, coremods are a no-go thanks for clearing that up

 

Wont using TESR for something like this become laggy if there are a lot of blocks? if so my main goal is really to just switch the texture of a block dynamically (and don't need any animation either) when a player walks too close to zones they're not allowed in yet.

 

I couldn't really find anything that suggests I can override a vanilla block which is kind of why I walked closer towards the dark arts of core mods 

 

I also want to keep the server vanilla, This way I can still allow vanilla clients along with an enhanced experience if people want to try out Forge.

Not as bad as you're thinking. You need thousands of them.  All being rendered at the same time. If the TE itself isn't ticking, it doesn't apply any impact.

You're not overriding a vanilla block, you're extending it.

Hahaha no.

While you could certainly tell Forge, "the client doesn't need my mod" and the client will connect, they're not going to see all the special blocks and items you've added.  This custom barrier block thing-a-jig you're making? That requires the code to exist on the client for it to work.

Well, this is just an enhancement mod for a vanilla server minigame, which is why i wanted to modify Barriers and various other things on the forge client to behave differently to vanilla (who dont see them at all).

 

Ill use TESR/FastTESR, it does sound like the easiest way so far.

 

Sorry for mixing the terms overriding and extending you're right (extending the class, and overriding the methods), it was just my heads way of explaining what i was doing 

 

Thanks for alerting me to TESR i probably would have done some unnecessary work if i didnt get told, saved me some future headaches

Sounds like an X-ray cheat in the making. I'm surprised this thread hasn't been locked already.

Nah, he's trying to do something else. I think.

Quite the opposite, I'm giving barrier blocks a forcefield view/sound upon reaching close proximity.

It's an enhancement mod for a vanilla mini game I'm working on.

[Zealock]

So im having troubles on where to begin, i just need help getting started, i can do all the render code my self im just a little unsure on what the procedure is..

 

Is it possible to render an overlay on the barrier block using an existing block texture, such as: Rendering the overlay obsidian over the barrier using tesr?

thanks
