[1.12.2] Fog Color/Fog Density

DiamondMiner88 · May 7, 2019

I cannot get the Fog color to work; along with the density. I looked at other posts, tutorials, and GitHub Repository-s but still have no idea why this won't work.

@SubscribeEvent(priority = EventPriority.NORMAL, receiveCanceled = true)
public void onFogDensityEvent(EntityViewRenderEvent.FogDensity event) {
    event.setDensity(0.0001F);
    if (event.getEntity().isInsideOfMaterial(ModMaterials.MOLTEN_GLASS)) event.setDensity(1F);
}

@SubscribeEvent(priority = EventPriority.NORMAL, receiveCanceled = true)
public void onFogColorsEvent(EntityViewRenderEvent.FogColors event) {
    if (event.getEntity().isInsideOfMaterial(ModMaterials.MOLTEN_GLASS)) {
        event.setRed(COLOR_MOLTEN_GLASS.getRed());
        event.setGreen(COLOR_MOLTEN_GLASS.getGreen());
        event.setBlue(COLOR_MOLTEN_GLASS.getBlue());
    }
}

private static final Color COLOR_MOLTEN_GLASS = new Color(251, 143, 70);

Did you check if events are being called?

No, how do i do that?

Well I am not an expert, but you can do that using debugger, orrr I always do that by simply putting

System.out.println("YAY It was called, so it's working!");

inside the method I wanna check.
I would suggest putting two checks - before if and after if - so you will get double result - check if your event is actually working (is it being called) and check if entity actually is inside that material, so you will be sure that your if works correctly.

V0idWa1k3r · May 7, 2019

FogColors likely expects the colour values to be within a [0-1] float range, not a [0-255]byte one

ItsWormy · May 7, 2019

Well, if you need to check, just do the getRed/Green/Blue method and see what it returns. And if you need to convert your RGB to a value between 0-1 range, it is as simple as dividing by 255.

Tried that in both Events returned nothing in console, Im going to try LOGGER.debug instead.

Hmmm.... could there be a problem with your events not being static? To be honest, not sure what the difference is between a static and non-static event is (I know the difference between static fields and methods).

so your events are not being called actually. Maybe try changing event methods to static?

Ok That fixed it. My other event subscriptions are static, didn't notice that. Now the problem is that the color is not working.

How it looks when I'm not in the fluid:

DiamondMiner88 · May 7, 2019

Ok Fixed that. Didn't know they had a difference.

When I'm in the liquid now this happens:

The clouds and horizon is the color i want to be, but blocks appear to be the same color, no difference.

By default the fog density mode would be linear. You would need to change it to exponental using GlStateManager in your density hook. I also believe that the density for lava is 2, not 1.

To be more specifically GlStateManager.fogMode

DiamondMiner88 · May 7, 2019

Assuming GlStateManager is a class, I can't find it. Doesen't show an option to import it. Im using IntelliJ

Edited May 7, 2019 by DiamondMiner88

V0idWa1k3r · May 7, 2019

net.minecraft.client.renderer.GlStateManager.

If you don't have this class then you are using 1.6 or lower. Or your setup is broken.

DiamondMiner88 · May 7, 2019

The font on this forum made me think that was a uppercase i not a lowercase L. Oops.

Its GlStateManager.setFog(FogMode mode)

Its it FogMode.EXP or FogMode.EXP2

V0idWa1k3r · May 7, 2019

Vanilla uses simple exponent for a lava fog I believe. It uses exp2 for water though. Play around with it to see which function suits you

DiamondMiner88 · May 7, 2019

I have done this in my density hook but it appears to have done nothing

GlStateManager.setFog(GlStateManager.FogMode.EXP);

I haven't finished the flow texture so i just set it to be white, here's how it looks:

Hmmm maybe you need to experiment with fogStart and fogEnd parameters?

            GlStateManager.fogStart(fogStartFloat-for e.g. 4f);
            GlStateManager.fogEnd(fogEndFloat for e.g. 40f);

DiamondMiner88 · May 8, 2019

Nope, didn't do anything.

ItsWormy · May 8, 2019

Try doing

GlStateManager.setFogDensity(float);

Look at what Minecraft uses for water (in net.minecraft.client.renderer.EntityRenderer):
