Cadan v2 - Progress Thread

[Geekboy1011]

Ok here we go. This is the new thread for progress on Cadan v2

Current Revision:v0.004a
Stable Download:N/A
Beta Download:N/A
Repository:https://bitbucket.org/CFD_LLC/cadan

Progress Summary:

Pre-2013-03-28 The year or so up to this point Cadan got its internal overhaul and was brought up to the 3 page app it is now.
2013-03-29 Cadan Got a repo on bitbuket managed by geekboy
2013-04-01 Debugging toggles added to make our lifes easier.
2013-04-01 Rearanged the player files for my sanity
2013-04-07 Got a completily new playershot handler mych saner and easier to work with
2013-04-08 Started importing player routines. New setup is nice
2013-12-14 Started working on this again. Another restructure. Might actually move some where this time

This title post will only be edited with major updates from here on out. The information at the top will always be to the latest available versions.
Want to help ask! want to comment and say its awesome go for it! want to lurk and be boring NO CHERRIES FOR YOU >:F

Well, for Iambian's arrival stuff like slowing down; I found these for the project:

Post indicating my appoval of this thread or something like that. Not entirely sure but I was asked to post something.


Right. Edit: Need info on fast algorithm for finding distance of a line given two coordinate pairs x,y

EDIT: Modification to this post has absolutely nothing to do with the topic. In fact, I was just looking for an old post that no one (should) notice to slip this file in as an attachment. Because other file hosting services suck. Shh... (NOTE: This file is source for an interrupt-based audio driver)

Edit: Need info on fast algorithm for finding distance of a line given two coordinate pairs x,y

What's the range of x,y? 0-63?

[Geekboy1011]

I believe so Calc.  Assume yes I'll text him later to confirm 

[Matrefeytontias]

Isn't the squared distance (X-Xyou)^2+(Y-Yyou)^2 ? I actually use that in IkarugaX, it's pretty fast and accurate.

As for Iambian's idea to quickly slow down and stop, I think I found the solution.

You start off with the 3 physics equations:
1) v^2 = u^2 + 2*a*d
2) v = u + a*t
3) d = u*t + .5*a*(t^2)

Where u = starting velocity (px per cycle)
v = final velocity (px per cycle)
d = distance from target
a = acceleration (- is deceleration)
t = time (so # of cycles??)

For your case you know u, v and d, and need to know a, so use formula (1), rearranged into:
a = (v^2 - u^2) / (2 d).

Then you can use (2) and (3) can then be used to calculate v and d at each time until arrival.

I expect Cadan v2 to support the bullet patterns and quantities detailed in the attached gif.

uhhhmmmm in theory it does >.> <.<

[Geekboy1011]

So a little update some eye candy with some routines Iambian developed for me.








all of these are functional because Iambian developed a routine that moves a players bullet based on a given angle. This routine will be used rather extensively among other characters this will be used for the dragons fire which needs to be re-coded as we made some structural changes that fixed some issues we were having but broke some old code

[annoyingcalc]

Erm WTF, that makes my mouth drool. -.-
Looking amazing tho

[Sorunome]

Now this is what you call awesome-looking!

[Matrefeytontias]

progress ! Looks so amazing

[TheMachine02]

yay    these routines look very cool

Geekboy: Thanks for letting me sit in on that coding session the other day and thanks for helping me understand flags!

(ya know, I'm actually quite interested in helping with this project now )
