How to Get Server Light Level

Recommended Posts

I'm making a slime block whose bounciness varies with light level. In order to do this, I need to override fallOn(), updateEntityAfterFallOn(), and StepOn(), and calculate the block's light level with them.

The problem is that my attempts seem to return the client-side light first, which is always 15 outside, even at night. More specifically, if I make the code return one value if the level is on server side and another on client side, I can see that both checks trigger in the log... but only the client side actually affects how bouncy the block is. I need a way to either get the server light from the client side, or a way to make the block's server-side behavior override its client-side behavior.

My code:

    @Override
    public int light(Level level, BlockPos pos, BlockState state) {
        if (level instanceof ServerLevel serverLevel) {
		int value = serverLevel.getMaxLocalRawBrightness(pos, 0);
                LogUtils.getLogger().info("Detected light level of " + value);
                return value;
        }
        else {
            int value = level.getMaxLocalRawBrightness(pos, 0);
            LogUtils.getLogger().info("Level not instance of serverlevel. Detected light level of " + value);
            return value;
        }
    }

As it turns out, what I needed was this:

        int value = level.getRawBrightness(pos, level.getSkyDarken());

My issue wasn't client/server, it was that I was inputting zero for the darkening factor instead of the sky darkness, which is how the game calculates nighttime and weather's effects on the light level.
