I'm currently using a custom dimension that has custom sky color.

 

WorldProvider: https://github.com/code4240/DarwinMod/blob/master/mod/Minecraft/src/code4240/alien/world/WorldProviderDarwin.java

 

The sky color code:

/*** Sky color ***/
        
    @Override
    public Vec3 getSkyColor(Entity cameraEntity, float partialTicks)
        {
         return this.worldObj.getWorldVec3Pool().getVecFromPool(0.6, 0.4, 0.4);
        }

    @Override
    public boolean isSkyColored()
        {
         return true;
        }
        
        @Override
        /**
* Return Vec3D with biome specific fog color
*/
    public Vec3 getFogColor(float par1, float par2)
    {
        float f2 = MathHelper.cos(par1 * (float)Math.PI * 0.6F) * 0.4F + 0.4F;

        if (f2 < 0.0F)
        {
            f2 = 0.0F;
        }

        if (f2 > 1.0F)
        {
            f2 = 1.0F;
        }

        float f3 = 0.7529412F;
        float f4 = 0.84705883F;
        float f5 = 1.0F;
        f3 *= f2 * 0.94F + 0.06F;
        f4 *= f2 * 0.94F + 0.06F;
        f5 *= f2 * 0.91F + 0.09F;
        return this.worldObj.getWorldVec3Pool().getVecFromPool((double)f3, (double)f4, (double)f5);
    }
}

 

This achieves the desired effect during the day. However, this color appears over the nighttime sky as well, and it looks hideous.

 

 

 

Daytime

 

Nighttime

 

 

 

Is there a way to make the sky color go away at night without overhauling the renderer?

The easy way is to implement your own SkyRenderer which is simple to do since WorldProvider has a way to set SkyRenderer for it's world.

That would be the easy way at least.

 

Although from what you need, couldn't you just use the world obj, and check which time it is before deciding the colors?

That works, but what I have is a very abrupt change:

 

@Override
public Vec3 getSkyColor(Entity cameraEntity, float partialTicks)
{
	if (this.worldObj.getWorldTime() < 14000) 
	{
         return this.worldObj.getWorldVec3Pool().getVecFromPool(0.6, 0.4, 0.4);
	} 
	else 
	{ 
		return this.worldObj.getWorldVec3Pool().getVecFromPool(0, 0, 0);
	}
}

 

How can I make the time fade from night to day and vice versa?

Well the time moves at a constant rate, so it always fades from night to day

 

As for the light, you have said if time is < 14 be this color and if time > 14 be that color.

What do you think you would have to do in order for it to fade?

I figured it was something like that, it's just that math is my worst skill and looking at math in general fries my brain.

 

The hardest part of it was dealing with the fact that sunrise range is (22000 -> 0 -> 500).

 

For anyone looking to do this, here's what I did:

 

@Override
public Vec3 getSkyColor(Entity cameraEntity, float partialTicks) {

	long time = this.worldObj.getWorldTime();
	float red = 1;
	float green = 1;
                // Green and blue use the same values in this instance

	// DAY
	if (time >= 500 && time <= 11500) {
		return this.worldObj.getWorldVec3Pool().getVecFromPool(0.6, 0.4, 0.4);
		}

	// NIGHT
	else if (time >= 14000 && time <= 22000) {
		return this.worldObj.getWorldVec3Pool().getVecFromPool(0, 0, 0);
		}

	else {
		//SUNRISE
		if (time > 22000 || time < 500) {

			// CREATE RANGE OF 1 - 2499
			if (time > 22000) {
				time = (time - 500) - 21500;
				// 1 -> 1999
			} else if (time < 500) {
				time = 2000 + time;
				// 2000 - 2499
			}
			red = (float) (0.00023999999999999998 * time);
			green = (float) (0.00016 * time);
		}


		//SUNSET
		else {
			red = (float) (-(0.00024019215372297838 * time) + 3.3624499599679742);
			green = (float) (-(0.0001601281024819856 * time) + 2.2416333066453165);
		}

		return this.worldObj.getWorldVec3Pool().getVecFromPool(red, green, green);
	}
}

Good job mate

Have fun modding!
