Hi Ken, I agree with you about RevOnline being a priority. Surly, if they haven't the time for that, they haven't the time to promote LC in education. If that should ever happen, I believe TG would have to be integral to LC, if it is to be taken seriously. Libraries do not provide the

ANN: Stars

As LiveCode announcements go, this one is pretty low key. All Stars does is provide the code for drawing a star. But there is a lesson for LiveCode to learn from the lowly five-pointed star, the one on the US flag. A star may be viewed in two ways: 1) Analytical Cartesian Geometry: A

Re: Sort of a problem

Thanks Peter. But I live in a very conservative county. None of yer fancy diagonals here. NW indeed! Actually it is the County election database, and a search reveals only N, E, S, and W. I think I finally get the phrase by of each. Live Code does pretty much what I did, except I'm sure

Sort of a problem

sorts in Live Code. I confess, I never understood them. Is there a custom sort available in Live Code to do this kind of sort? Thanks, JIm Hurley Here is the bubble sort: on mouseUp put field 1 into tList put N E S W into tWordsToIgnore put the number of lines in tList into n repeat

Re: Animation

Hi J, LC can handle the game of 9 ball pool fairly well, and that is fairly computationally intensive--handling the collisions between multiple moving balls. You can find it at http://jamesphurley.com/Revolution.html To download a stack from that web site, get the link and run this in the

Re: ANN and OT: Calling All SETI Enthusiasts

Roger and RIchard, Two more distinctions: 1) Theories that supersede vs. theories that overturn The General theory of relativity superseded Newton's theory of gravity and QM superseded Newtonian dynamics. In each case, the second is the classical limit of the first. On the other hand,

Re: Collisions

Richard, That 9 ball stack is a bit wonkish. I have extracted from that stack the basic elements that illustrate the collision process. It can be found in: go url http://jamesphurley.com/jhurleyFolder/TwoBallCollisions.livecode; It illustrates the physics of the ideal collision. The
