Note for you, Horizon Component System broke in 1.7. It cannot perform a radar lock so it can't dodge/fire effectively.

Welcome to the wiki indeed! About Horizon, maybe Horizon is fixed as of 1.7.1 Beta2? I haven't tested 1.7.1 Beta2 yet. And Nat, any reason you haven't made a bug report for it or is it the same bug as one already reported? --[[User:Rednaxela|Rednaxela]] 03:21, 13 March 2009 (UTC)

Okay, I'm almost done with the prototype of my bot. It's really big, so I'll put it [[PwnBot/Current_Code|here]].  I'm sure it has lots of problems with the antigrav movement, (just look at the console, which shows the x force and y force that the points generate) and I'm sure it doesn't work at all... However, do take a look at the debug graphics, I think they're cool. =)

Um... I do have one problem. Whenever I try to use things such as GF targeting, Surfing, etc. The tutorials never use the methods properly or something. It gives a can't find symbol error for every custom method in the code. =/ -- [[User:Awesomeness|Awesomeness]]

:OH NO!  Something I did with the antigrav code messed up the bullet sim code!  Good thing I backed up the non-broken version before I added antigrav. Should I show that one instead?

The compiler ALWAYS gives me errors unless I set it to "-classpath /Users/student/Documents/Robocode/libs/robocode.jar".  Maybe that's cuz I use a mac.  [[User:Awesomeness|Awesomeness]] 14:36, 13 March 2009 (UTC)

:: It would look through every branch in the tree, and it will look for matches.  It simply takes the current speed, acceleration, turn rate, etc. and finds the closest match, or matches.  If there are multiple branches that match, it would take the branch that occurs most.  I suppose if they're even in occurence it might pick them randomly.  Then again, it might balance out, choosing based on the closeness of the match and the number of occurences combined.

== Trigonometry Question ==
 
−
 
 
−
Ok, this is kind of unrelated, but all you guys here are experts at trigonometry,and although I go to a VERY advanced school, I'm only 13, and I have a limited understanding.  I am making a java application totally unrelated to Robocode.  Say I have this scenario:
 
−
 
 
−
I've made a dot that moves around with the arrow keys, but I want another dot to follow it.  I've made the first dot move according to the arrow keys, and I could make the follower dot's movement simple, but I want it to move DIRECTLY towards the arrow key mover dot.  To do this I need two things:
 
−
 
 
−
-A method returning a double and taking parameters x, y, x2, and y2 giving the angle in radians between them in comparison to vertical.  For example, if x and y are 0, 0 and x1 and y2 are 2, 2, then the angle you'd get is 2.35619449, or 135 degrees in radians.
 
−
 
 
−
-A way to get the change in x and y when given an angle.  It returns x and y and takes a double called angle.  For example, if the angle was 90 degrees, (in radians, though, of course) then it would return 1, 0, if it was 180 degrees, it'd return  0, 1, and if it was 270 degrees it'd be -1, 0.

Sorry if this is confusing...  Someone help, please! --[[Awesomeness]] (moved by --[[User:Zyx|zyx]] 01:24, 29 March 2009 (UTC))

* That first method is equal to Math.atan2(x2-x1,y1-y2). --[[User:Rednaxela|Rednaxela]] 01:27, 29 March 2009 (UTC)
 
−
 
 
−
* For the second method, your first value would be Math.sin(angle+Math.PI), and the second value would be Math.cos(angle+Math.PI). (Keep in mind that you can't return two values from one method unless putting them in an object/array or something) --[[User:Rednaxela|Rednaxela]] 01:31, 29 March 2009 (UTC)

(edit conflict)
 
−
 
 
−
* Although [[Rednaxela]] already answered, I believe he's methods may be too Robocodish, as I think he still has the rotated Math we use here. But I may be wrong.
 
−
 
 
−
* First let me clarify. I think you have the 0,0 on the top left corner, am I right? That's the only reason I would understand your results for question1, and probably makes sense since you are using display coordinates.
 
−
 
 
−
* Being that the case, the first method is something like this
 
−
<pre>
 
−
double angle(double x, double y, double x2, double y2) {
 
−
  double alpha = Math.atan2(-(y2 - y), x2 - x);
 
−
  return Math.PI / 2 - alpha;
 
−
}
 
−
</pre>
 
−
:see that atan2(y, x) will give you the angle from origin (0,0) to (x, y). The minus sign in the y parameter is to account for the fact that 0,0 is on top left and not bottom left as in regular math. PI / 2 should be the vertical vector you mention, the may need some tweaking, but they are small if any.
 
−
 
 
−
* For the second method, I will give a hint and let you try work it out. The sine of an angle represents the y-axis, and the cosine is x-axis. Try working out them for your fits. Use a calculator to check the values, Windows calc can handle sin/cos of Degrees or radians, and most scientific calculators do as well.

[[Rednaxela]] methods are not in Robocode coordinates, are actually in display coordinates, so probably are more direct to your needs. --[[User:Zyx|zyx]] 01:56, 29 March 2009 (UTC)
 
−
 
 
−
I believed [[Rednaxela]] method are robocode's, not trigonometry standard. But robocode use the same coordinates system as same as java awt/swing component. Anyway, don't use [[Rednaxela]] in your math class! In math class you should do [[Zyx]]'s. Another thing, standard/java's 0 degrees would be at right but robocode use top, so beware when you write robots that you should switch sin <-> cos and atan2(z,x) to atan2(x,y).
 
−

One more thing, you said "I'm only 13, and I have a limited understanding." I don't know where do you learn (you say very advanced school, but I'm in advanced school, too), but I'm 13 too and understand a lot of trigonometry already (well, not all. I still have some problem, too.) yet I have not learn that in classroom (but learn from some other source, including robocode) Trigonomatry is not hard, as I and my friends taught another friend within 10 minutes and that include all basic sin/cos/tan and the inverse. &raquo; <span style="font-size:0.9em;color:darkgreen;">[[User:Nat|Nat]] | [[User_talk:Nat|Talk]]</span> &raquo; 06:33, 29 March 2009 (UTC)

* Incorrect Nat, the methods I listed are ''not'' for robocode style angles/coordinates, they are for the style that [[User:Awesomeness|Awesomeness]] very specifically requested. It was quite specifically said that 0 degrees should be up, and 2, 2 should be 135 degrees. Which is neither robocode-style nor standard-trig-style, but is the style I set those methods up to use. --[[User:Rednaxela|Rednaxela]] 06:47, 29 March 2009 (UTC)
 
−
 
 
−
* Yes [[Nat]], I was confused at first too, but they are quite what asked for. The first method should give the same results as the one I posted, but his method takes care for the 0 being on top more directly than I did; and I don't think that matters in this case, but is faster than mine :-). --[[User:Zyx|zyx]] 10:51, 29 March 2009 (UTC)

** Well well, I know that Rednaxela method are what Awesomeness want, I just warn him not to use your method in his math class or in other place. Also, in old wiki, there is said somewhere that this style is robocode's, but I know that this is what Awesomeness want :-) &raquo; <span style="font-size:0.9em;color:darkgreen;">[[User:Nat|Nat]] | [[User_talk:Nat|Talk]]</span> &raquo; 13:28, 29 March 2009 (UTC)

** This style ''isn't'' quite robocode's. In robocode, 0 degrees is up AND 2,2 is 45 degrees not 135 degrees. Inverted y axis from robocode in other words. --[[User:Rednaxela|Rednaxela]] 15:37, 29 March 2009 (UTC)
