Breeding two different animals

[Dren]

Hi!

I created a Bull entity which should breed with the cow ... but I don't know how to do this. I spent six hours trying different methods but nothing changed.

 

Would you help me please?

[Mazetar]

How about telling us what you have tried?

[Dren]

How about telling us what you have tried?

 

I tried to edit the code "canmatewith", i tried to create a custom AIMate for cows and bulls, i tried to create a custom "canmatewith" code for cows and bulls ... T_T

[Mazetar]

When u debugged the canmatewith method which you overrided, what happend when it was called?

[SenpaiSubaraki]

what about extending entity bull by entity cow ?

so the bull gets recognized as a cow, not another entityliving.

 

dont know if that works though.

o_o

uhm. Nothing happens ... I show you the AI i created and the canmatewith custom i made:

 

 

canMateWith

 

 

	public boolean canMateWith(EntityAnimal entity){
    	if (entity == this){
    		return false;
    	}else if ((this instanceof BullEntity) && (entity instanceof EntityCow)){
    		return this.isInLove() && entity.isInLove();
    	}else if ((this instanceof EntityCow) && (entity instanceof BullEntity)){
    		return this.isInLove() && entity.isInLove();
    	}
    	return false;
    }

what about extending entity bull by entity cow ?

so the bull gets recognized as a cow, not another entityliving.

 

dont know if that works though.

 

I thought of this as well but I just want cow and bull to breed, not cow and cow or bull and bull T_T

 

[Mazetar]

nothing happends? as inn the code is never called? the breakpoints never seems to be passed or?

The cows keep mating each others, as well as bull; bulls and cows don't mate.

 

It's like the mod doesn't see my changes.

 

Sorry for my bad english

[Mazetar]

Thats not what I asked, I asked what happends when the code execute, when the code runs. What happends the exact moment each line of code runs trough the method?

 

Not what you see in-game but what do you see inn the code when it checks cow against bull?

 

If you can't tell me this, I promise you what you really need above and before all is to learn some programming somewhere before modding a game..

[Mazetar]

let me be even more specific inn my question:

 

What happends when THIS line is run?

}else if ((this instanceof BullEntity) && (entity instanceof EntityCow)){

Do you know what this code is checking for?

The mod doesn't get to that point

 

 

[Mazetar]

why does it not, what prevents it from hitting that line of code?

and justa s important: Do you understand what it would do IF it hit that line?

[pdogmuncher]

I know this thread has been closed for a while, but for anyone who has this problem, SenpaiSubaraki's suggestion works. Make one of the entities extend the other, then use the canmatewith method code Dren created in each of the entities.
