HI,
Not a single problem with working alone. But keep in mind that in many
occasions you get more exp working in groups. And later on the quests and
monsters get tougher so grouping is advised.
BTW, what is the name of your character in Alter?

Hey Kara, this is super. I can actually follow this without getting too
lost. It makes me think of what some games, like Lone Wolf may go
through when David programmed it.
However the first thing i thought of when I read the message from you
was the following.
What's your vector Victor. This is Captain Over over. Roger Roger, huh?
What?
Take care.

Hi all,
Well I'm done responding to list craziness and since you get what you
focus on, I'm focusing on cool game mechanics! :)
I'd like to take my earlier notes on vectors and such, a step further to
a process called projection.
When you project a vector on to another vector, you're simply adding the
components of one vector to the components of another. As in:
0,2,0 + 1,0,0 = 1,2,0
So this process is just adding the x, y, and z components of each vector
separately as in:
0 + 1 = 1
2 + 0 = 2
0 + 0 = 0
So this is great but why would we want to do this?
Let's think of the first vector above (0,2,0) as perhaps a boat on an
ocean. This boat is traveling north in our game world, at 2 units per
some amount of time.
Let's think of the second vector as a wind blowing toward the east at 1
unit per some amount of time. You can see where I'm going with this. ;)
If we apply the wind to the boat's motion, we end up with the boat
traveling to the coordinates 1,2,0 at the end of our given amount of
time.
If the boat captain continues to steer the boat due north at the same
speed (0,2,0) the wind will still be blowing due east (1,0,0) and thus
again blow the boat to the ending coordinates of (1,2,0) again as the
next unit of time passes.
We can actually use projection to simulate various forces acting on
entities in our game world; wind, thrust, gravity, drag, friction. etc.
Let's look at the above projection in a different way now. Instead of the
boat captain steering the boat against the wind, perhaps the captain is
asleep and the boat is adrift. Don't worry, we won't let him go very far.
:)
So we have our boat starting out moving north at (0,2,0).
We have our wind steadily blowing at (1,0,0).
Project the wind on to the boat's motion and you end up with the boat at
(1,2,0)
What happens if the boat simply keeps moving in its new direction?
1,2,0 + 1,0,0 = 2,2,0
Our boat is now moving northeast. -And the wind keeps blowing.
2,2,0 + 1,0,0 = 3,2,0
Our boat is now traveling east-northeast.
This looks right at a glance, but let's look at what's really happening
here. If you notice, our boat is actually speeding up and our
calculations are off.
Even though the above looks like physics, we haven't really taken any
physics into account here. -And, rather than go into a lot of physics in
this note, let's stay with a simple aspect of this boat's travel.
In an earlier note I gave the example of a runner continuously
accelerating and we illustrated this with an ever-increasing vector
length. Well if you notice, our boat's vector of travel keeps getting
longer as the wind keeps blowing. If we kept projecting the wind vector
on to the boat's travel vector, the x coordinate would just keep in
creasing and increasing and increasing until our boat would basically be
traveling faster than any other boat I know of! :) -And it still wouldn't
stop there! :)
Obviously a wind of only 1 unit over time shouldn't be causing another
object to go faster and faster and faster.
So what have we missed? We haven't been taking the length or magnitude of
our vector into account.
So how does this help us?
We know that our boat originally traveled at 2 units over time. So our
boat;s vector of travel has a magnitude of 2 units. When we project the
wind vector on to it, we are adding magnitude to the vector.
Remember we ended up with 1,2,0
So rather than leave it there, let's check the magnitude of this vector.
We do this with the Pythagoras theorem.
1 * 1 is 1
2 * 2 is 4
0 * 0 is 0
1 + 4 + 0 is 5
the square root of 5 is 2.23606797749979
2.24 for our uses?
So our boat is now traveling faster than it's usual 2 units. As I said,
we can take quite a lot into account here but for now let's just go with
the idea that we really only want our boat ever traveling at 2 units over
a given time.
We can magnify our current vector so its length (the boat's velocity) is
still 2 units but traveling in its new direction.
Remember, we do this by dividing our vector by it's current length and
then multiplying by the length we want it to have.
So this would look like:
1 / 2.24 * 2 = 0.8928
2 / 2.24 * 2 = 1.7857
0 / 2.24 * 2 = 0
So the vector of travel we end up with is:
0.8928,1.7857,0
Okay, so it's just not as pretty as our earlier vectors but the computer
doesn't care. it will still be able to work with it just as effectively
in a gaming situation.
So this is actually the new direction and speed of our boat as the wind
blows it.
NOw we can do more with physics to take into account the energy being
imparted to the boat from the wind as well as the drag on the boat from
the sea and such, but for now this should be a fun start!?
Vector projection is a really simple, useful and pretty interesting
process to play with with your game entities.
Hope this makes sense and is something y'all may be interested in? :)
Have a great weekend and talk with y'all soon!?
Smiles,
Cara :)

His name is Loren. He's a Mage/ClericThief who's at tis moment tring to
complete the quests in Bandera Azul.

I'm inBandera Azul i Alter Aeon and I'm having trouble finding who to
talk to to start a couple quests. I completed the one where I teach the
punk kid a lesson, but I can't seem to find the one about finding the
lost child and the one about the kitten. Of course I'll be taking the
good path for both (and anyway being a cat person in real life I could
never imagine eating one). But since most everybody in that village
speaks Spanish or an approximation thereof I'm not sure what to do. I
posted on the Newbie channel but all tey said was tat important people
speak English. The problem is I found maybe two or three such people and
none of them seem related to these two quests.
