[1.14] Custom Night Vision Effect


Recommended Posts

Hi, I ran into a problem:


The night vision's effect of brightening up the surroundings is handled in LightTexture#updateLightmap(float partialTicks) and checks for the potion effect, after which a value (usually 1, if the effect is about to expire 0.7 + a sinus curve) is retrieved. How would I implement my own night vision effect, say, at lower intensity? I don't think it's possible to change that vanilla method to account for another check.

AFAIK there is no proper way of doing so.


One wild idea would be to create a custom implementation of LightTexture, and override LightTexture#updateLightmap to take your custom potion effect into account. Then use reflection to change the lightmapTexture field in GameRenderer (from the field gameRenderer in the Minecraft instance from Minecraft#getMinecraft) to an instance of your own LightTexture.

However I am sure this will break many things and might not work as intended.

Personally, I would just use the normal night vision effect.

Some tips:


Modder Support:


1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.



Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.



The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:


1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.
