Flower that glows at night, not in the day

[Zedicus]

This should give you the time based on the current angle of the moon and such.

 

Minecraft minecraft = Minecraft.getMinecraft();

if (minecraft.theWorld != null) {
    float time = minecraft.theWorld.getCelestialAngle(1.0F);
}

 

I believe this is more or less what the clock does for it's texture.

It's also how the daylight sensor tells day from night.  WorldTime % 24000 should also work.

Lighting up in the dark "and being bright all the time" are largely indistinguishable, because of the way lighting works.

How would this be added to the code provided by draco18s?

Technically the code I use makes a call to getCelestialAngle.  Just not directly:

 

World.java

public int calculateSkylightSubtracted(float par1)
    {
        float var2 = this.getCelestialAngle(par1);
        float var3 = 1.0F - (MathHelper.cos(var2 * (float)Math.PI * 2.0F) * 2.0F + 0.5F);

        if (var3 < 0.0F)
        {
            var3 = 0.0F;
        }

        if (var3 > 1.0F)
        {
            var3 = 1.0F;
        }

        var3 = 1.0F - var3;
        var3 = (float)((double)var3 * (1.0D - (double)(this.getRainStrength(par1) * 5.0F) / 16.0D));
        var3 = (float)((double)var3 * (1.0D - (double)(this.getWeightedThunderStrength(par1) * 5.0F) / 16.0D));
        var3 = 1.0F - var3;
        return (int)(var3 * 11.0F);
    }

In my version I have a boolean method that checks if the value of WorldTime % 24000 > 13100, which I am considering to be night. Then I query that method before triggering the change.

 

For what its worth, Draco18 appears to be a more experienced modder (and a more scrupulous coder) than myself, so it's probably wise to use his approach even after I post my version. My code often contains an alarming amount of ghetto.

I've been modding for about two weeks. o..o;

As for scrupulous...not sure.  I just use the code hinting excessively.  "Is there a function to do...?" and check the various objects I have access to.

 

Also, I figured out I didn't need to save a reference to the World.  World implements IBlockAccess, so you can pass it to your lighting function from within updateTick:

 

public void updateTick(World world, int x, int y, int z, Random par5Random) {
     getLightValue(world, x, y, z);
}

 

And you do need to call that function in the update, or it won't be recalculated.

Just take the compliment. 

 

I'm working on a version that fades on and off. Might be way system intensive, but I'm just going for proof of concept.

I'm too humble to do that.  Thhhb.

@Override public int getTextureFromSideAndMetadata(int side, int metadata)

 

Just return a different value when metadata isn't zero.

Thanks for all your help guys, I really appreciate the response I have received about the topic. Just a question though, It was mentioned that if the flower didnt spawn to commonly or wasnt generated throughout the world I could use a tile entity and it may be better. Well as some may have noticed I also asked another topic question about adding custom villager trades....Well as it turns out I plan to add this and several other aspects of the mod to custom trades. So the question is, as there really arent any good references for those that have never done it, how do I set up custom trades in forge, the modloader method does not work in forge, and shouldnt be done that way anyhow I know. But if it is better to use a tile for the flower and this is going to be a custom trade I would like to know how the tile would be set up for it (as I am sure others would too) and I would also need to know how to set up the forge VillagerRegistry method for doing this. I have tried and failed miserably at getting this to work. I have several flowers that are for trades, along with several other items. You guys are great, and I hope this isnt to forward of a question....and if you so desire to see the mod coming along it is here....

at night, and i was wrong ti does seem to work but it only updates its light value on placement i waited for 5 minecraft days and it didn't change its light-value once?

You need to force the calculation manually via updateTick.

[ashtonr12]

i have this fomr the code before

public void updateTick(World world, int x, int y, int z, Random par5Random) {
  if(theWorld == null)
   theWorld = world;  //make sure theWorld is not null
  getLightValue(null, x, y, z); //force recheck of light level, probably not needed
  world.scheduleBlockUpdate(x, y, z, blockID, 600);  //schedule another update
 }

but it doesnt SEEM to work

It would be pretty cool if you could figure out how to dynamically change the light value, as that would allow you to make it pulse softly in the dark, or slowly fade "on" at twilight, instead of turning on abruptly like a light switch.

 

I like this idea, and I'm half tempted to code it and post it here.

 

I wish someone would help, I have been trying for almost 3 weeks and this is best I got

 

Cant we just make two flowers (flower_Unlit and flower_Lit) after a few ticks it will change the block from lit to unlit and vice versa
