setVelocity - Vector

Hi!

With setVelocity i can make that a zombie move to a location. but how? If i make setVelocity(loc.toVector()); its not work...

 

Try something like new Vector(1, 0, 0);
You have to give directions, not coordinates. The example above should move the mob on the X axis. If you want to move backwards just use negative values.

 

Thanks! And, if i make: new Vector(5,0,5) its move diagnonaly 5blocks?

 

I'm really not sure about the numbers, I never really worked with vectors. Maybe 0.0005 is more than enough, maybe you need 50000, no idea. Just try&error? But yes, if you set two values it moves diagonally.

 

Ok! And another question: how i can get the direction from a location to antoher location? because i have one location (a spawnpoint) and i would that the entitys move to the another point - but for that i need the direction from loc1 -> loc2 ...

 

I know that a vertical velocity of about 0.37 is equivalent to a normal player jump. Assuming horizontal velocities are the same (I imagine they would be), then a velocity of (5,0,5) will send your zombie southwest at extreme speed

For getting the direction from location A to location B, this should work (untested):

PHP:

Vector dir = locB.toVector().subtract(locA.toVector()).normalize();
// dir is now a unit vector pointing from A to B
// set "speed" to how fast you want the entity at A to move towards B
entity.setVelocity(dir.multiply(speed));


 

Position 1 = X1, Y1, Z1
Position 2 = X2, Y2, Z2

As far as I remember (maybe you should try looking at vector in maths) direction vector from 1 to 2 is:
Position 2 - Position 1 = X2-X1, Y2-Y1, Z2-Z1

You have a vector that contains a direction but the magnitude is high, I'm not sure how this Vector thing no the code will work, but I can say the magnitude of the vector will give the zombie the speed, not the direction, but I don't know what relation have the magnitude itself with the speed

Yes that probably will work.

Yep, you have it - you just need to normalise the vector to get a unit vector in the right direction, which you can then multiply with your desired speed - see my code snippet above.

Edit: simultaneous post, pretty much?

 

Hahahah, while I was doing the first post u made urs, then I replied

Bro, do you know the speed thing? I mean what values are the ones for normal speeding and stuff? thats an interesting thing I would like to check out

 

Thanks! But the entity, on spawning, not move to position b - just one block, in the direction to b, not more :/

 

kinda late but it may help you, you need to multiply it to set speed.
