Eclipse renaming classes already being used by another package

I still don't know if it's just my computer, or a bug in my eclipse.  Screen shot on bottom.

Eclipse doesn't like it when you rename a java project/class that is being used in another project/class.

I deleted the old project to try and fix the bugs I was getting, but it still told me that the path for that class didn't exist even after renaming, and renaming them all in the main file I was trying to run.

What I had to do to fix it:

After I got the new name by deleting the old java project, and creating a new one with the new name:
(and renaming the class) (I just copied and pasted the it into a newly created java project)

I had to right click the main file I was running, and go to properties:
Go to java build path
Go to projects
Remove all references to the missing project from the list
Add the newly named project to that list.

Hope this helps!

playing with color in powershell python

Here's a bit I'm working on.  I've discovered I love doing Ascii.  Examples of how to use the color changing escape.  I got a table from StackOverflow: https://stackoverflow.com/questions/287871/print-in-terminal-with-colors-using-python the charts are way at the bottom. So far accurate for me.  def prettyjunk ( self ): # 1 is bold, 0 is plain, 2 is dull text_red = ' \x1b [1;31;40m' stop_color = ' \x1b [0m' text_blue = ' \x1b [1;34;40m' text_green = ' \x1b [1;32;40m' text_purple = ' \x1b [1;35;40m' text_lightblue = ' \x1b [1;36;40m' text_white = ' \x1b [1;37;40m' a_green_at = ( f " { text_green } @ { stop_color } " ) a_red_at = ( f " { text_red } @ { stop_color } " ) print ( f " { text_red } This should be Red. { stop_color } " ) print ( f "

JavaScript Ascii animation with while loops and console.log

I was working on figuring out while loops for an exercise in LearnJavaScriptTheHardWay  by Zed Shaw,  and I decided to do this: The red text console.logs were for debugging, and will take over the animation if the comments are removed. The bold red number is the point at which the loop stops.  My CPU didn't have too much trouble with that large number, but I'd recommend dialing it down if your CPU is slow. Also if your CPU is really fast, you'll have to change the pause to something much lower to see the animation better.  That too is in a loop, so the more that pause happens, the more loops your CPU is running.   Link: https://stackoverflow.com/questions/9006988/node-js-on-windows-how-to-clear-console To clear screen as described in link above, uncomment the bold purple comment I tried to comment the code to help learners see what I did,  any comments or suggestions, feel free to drop em in!                      ex16_ASCII.js //Trying to make a comma

playing with trigonometry sin in pygame

Image
Ok I am so far from understanding, so don't take this as any kind of math lesson. Also, every time I thought I knew what I was doing.... pygame would show me differently. Still a work in progress, but for now, something to play with. Update: SinWaveTime class added to produce that particular weaving effect Tinkering with the different sin wave variables: I wrote this piece separate from my 3D experiment to see how to manipulate the sin wave. While trying to use time as the factor to move my pygame draw circle on the x-axis, i got this crazy little doo-dad : I don't think it's drawing two circles at once, but if I figure out what the heck it's doing I'll let you know.  Or hey if you know, drop a comment.  I don't know if my comments are just not working, or no one wants to. So, here's some pygame code to play with the sin wave.  Alter the different variables to see it in action. picture of SinWave.move_with_time() see changes, SinWaveTime c
