transparent block preview

[Reset]

Hi guys 

I am working on a mod that helps building things in creative, kind of like WorldEdit, but with fancy guis and stuff.

Now my question:

Is there a (simple) way of rendering blocks with about 10% alphachannel as a preview?

This was my inspiration:

I just want the preview to show, which block it will become.

Thank you for your time!

yes, do you have a good understanding of java and opengl ?

Java and opengl in 2d definitely.

In 3d, i might  need some time

fiouf, this will be a bit easier (also opengl 2d and 3d are technicly the same thing, except for rotation matrxi and projection matrxi that are a BIT more complex in 3d)

 

if the "alpha" block are not created, you can use a proxy to store shapes  that represent the block in the world and create entities that will be rendered like blocks

 

if the block are created it would be a pain to render them with alpha so i suggest that instead you draw a box over all of them using entities again

 

btw what you're asking is VERY big so you will need to do a lot of research. if you havnt checked yet i suggest you take a look at the wiki for entity because i think they will greatly help you.

 

also modders github are very usefull to learn from real code
