Hey, I got a question. Is it possible to add icons (not clickable buttons) to a gui screen that switches to a different one when a condition is met? By the way, the gui screen is opened from an entity and the condition is whether the entity is a female or a male (something I'm trying out to make breeding more realistic and to make it easier to address the entity since it is a tameable entity).

Is it possible to add icons (not clickable buttons) to a gui screen that switches to a different one when a condition is met?

 

Yes.

 

drawModalRect

You could just create the gui with a different texture depending on what opened it.

Is it possible to add icons (not clickable buttons) to a gui screen that switches to a different one when a condition is met?

 

Yes.

 

drawModalRect

 

Hey, I got this:

		this.drawModalRectWithCustomSizedTexture(x, y, u, v, xMouse, yMouse, textureWidth, textureHeight);

 

So what do I put in these parameters?

Exactly the same as you would for drawing the progress bar on a furnace, only the size isn't changing, just the uv coordinates based on your state.

Oh wait, I found something else

 

		this.drawTexturedModalRect(x, y, textureSprite, p_175175_4_, p_175175_5_); 

 

But with this, I need something that is a TextureAtlasSprite.. I tried making something you would with the ResourecLocation class but it's not visible. And also for the other method, where would I get these states from?

YOU are defining the states.  It's some property of the entity you're displaying information for.

Ok, I started on something like this but I don't see the texture

 

	public static final ResourceLocation male = new ResourceLocation(Constants.modid + ":" + "textures/gui/maleFemaleButtons.png");
...

	mc.renderEngine.bindTexture(male); // TODO
	this.drawTexturedModalRect(topX + 20, topY + 20, 0, 0, 2, 2);

 

Here is the textures I want to be able to see:

http://i1319.photobucket.com/albums/t661/Nova_Leary/maleFemaleButtons_zpsg0poboz5.png[/img]

Nvm, I fixed it and also, how do I make it randomly set a gender when the entity spawns?

There is Random class for a reason.

 

Don't make new one. Use random field in either entity or world.

I started this.. but with no success

 

DataValues and NBT

	@Override
protected void entityInit() { // TODO
	super.entityInit();
	this.dataWatcher.addObject(DataValues.gender, Byte.valueOf((byte)0)); //Gender
}
//@formatter:on
@Override
public void writeEntityToNBT(NBTTagCompound tagCompound) {
	super.writeEntityToNBT(tagCompound);
	tagCompound.setBoolean("gender", this.isMale());
}

@Override
public void readEntityFromNBT(NBTTagCompound tagCompound) {
	super.readEntityFromNBT(tagCompound);
	this.setMale(tagCompound.getBoolean("gender"));
}

 

Methods

	public boolean isMale() {
	return (this.dataWatcher.getWatchableObjectByte(DataValues.gender) & 2) != 0;
}

public void setMale(boolean isMale) {
	byte b0 = this.dataWatcher.getWatchableObjectByte(DataValues.gender);

	if (isMale) {
		this.dataWatcher.updateObject(DataValues.gender, Byte.valueOf((byte) (b0 | 2)));
	}
	else {
		this.dataWatcher.updateObject(DataValues.gender, Byte.valueOf((byte) (b0 & -3)));
	}
}

public boolean isFemale() {
	return (this.dataWatcher.getWatchableObjectByte(DataValues.gender) & 4) != 0;
}

public void setFemale(boolean isFemale) {
	byte b0 = this.dataWatcher.getWatchableObjectByte(DataValues.gender);

	if (isFemale) {
		this.dataWatcher.updateObject(DataValues.gender, Byte.valueOf((byte) (b0 | 4)));
	}
	else {
		this.dataWatcher.updateObject(DataValues.gender, Byte.valueOf((byte) (b0 & -5)));
	}
}

 

Event

	@SubscribeEvent
public void genderSet(LivingSpawnEvent event) {
	if (event.entity instanceof EntityZertumEntity) {
		EntityZertumEntity dog = (EntityZertumEntity) event.entity;
		if (dog.getRNG().nextInt(3) == 0) {
			dog.setMale(true);
		}
		else {
			dog.setFemale(true);
		}
		System.out.println("Is Male?: " + dog.isMale() + " Is Female? " + dog.isFemale());
	}
}

I changed the gender tasks to these

 

 

DataValue

	@Override
protected void entityInit() { // TODO
	super.entityInit();
	this.dataWatcher.addObject(DataValues.gender, new String("")); //Gender
}

 

NBT

	@Override
public void writeEntityToNBT(NBTTagCompound tagCompound) {
	super.writeEntityToNBT(tagCompound);
	tagCompound.setString("gender", this.getGender());
}

@Override
public void readEntityFromNBT(NBTTagCompound tagCompound) {
	super.readEntityFromNBT(tagCompound);
	this.setGender(tagCompound.getString("gender"));
}

 

Methods

	public void setGender(String gender) {
	this.dataWatcher.updateObject(DataValues.gender, gender);
}

public String getGender() {
	return this.dataWatcher.getWatchableObjectString(DataValues.gender);
}

 

Update Event for Gender

		if (this.isEntityAlive()) {
		if (this.rand.nextInt(2) == 0) {
			this.setGender("male");
		}
		else {
			this.setGender("female");
		}
	}

I want it where the entity randomly selects a gender when it spawns, but I have this event so far in onUpdate() in the entity. How do I make it randomly select the gender ONLY one every time it spawns?

I changed it because it was harder to use the bits like the tame methods did. What I want the entity to do is start a randomizer to select either female or male ONLY once, once i start it though it never stops.

*shudders* Copy pasted bitmasks used wrongly... Great.

 

What does that mean?

But would it go on forever in entityInt and make the methods I have useless since it comes before the NBT write and read?

Setup ONE DataWatcher for this entity with BOOLEAN (true = male, false = female).

In entityInit (or constructor):

1. You generate 1 or 0 value using Random (on how to use it - look vanilla or google it) -> setObject (DataWatcher of gender) to true or false depending on what you randomed.

In readNBT do:

1. check if nbt has boolean "Gender" key.

2. If it has: setObject (DataWatcher of gender) to true or false (from vale of "Gender" key) -> DONE

3. If it doesn't have this key - it means it was never set! DONE (genders that were not set are alredy handled by constructor)

4. DONE

In writeNBT:

1. you getObject from DataWatcher - you get boolean value of 1 or 0 and save it using nbt.setBoolean("Gender", gender);

Thanks, that works perfectly and the icons switch exactly

Oh and now my question, how do I have the mating methods check for the genders?

Are you using EntityAnimal?

 

There is:

    public boolean canMateWith(EntityAnimal otherAnimal)
    {
        return otherAnimal == this ? false : (otherAnimal.getClass() != this.getClass() ? false : this.isInLove() && otherAnimal.isInLove());
    }

 

You can use it to check whatever you want

Yeah and let me try it out

And it works! Thanks guys!

Whoooooa wait, I noticed something whenever I leave and came back to the same world OR close the client and come back, the genders of the entity change to opposite ones

Well, I noticed that Jamie is now dating Kate who just broke up with Steve, who turned out to be Gay after 5 years of relationship.

You don't understand who those people are, do you?

 

The point is - we don't know your code.

No? Well, for some reason when the world loads up, the randomizer starts up again and switches the genders

Loading NBT happens after constructor, therefore if you are loading boolean and putting it into dataWatcher after initialization of entity, I don't really see posibility.

 

Post code.

I am out for today (~7 hours), so don't wait
