1. Re: bullet code (was ICONS - dead horse)
I have found some errors in your equations. If you are going to tell
me that my code looks like chicken scratch at least have your information
correct. I was just looking to see if I maybe overlooked something. I am
new to programing. I have only done one program in euphoria. Maybe two in
qbasic. You seem like a very lighthearted person so don't
take this the wrong way.
you wrote:
y=vy*t - .5*g*t*t
In dealing with a "projectile" that is launched horizontaly(I'll get into
angles later) there are
two simple equation for x and y axis. They are,
x axis:
x = v * t
y axis:
y = .5 * g * t^2
This is all you need. Where your equation above for 10m/s at 1 sec tells
us that the object fell 5.1 meters the one I use (that I got out of a
physics)
book marks the object at 4.9 meters. I believe what you have there is
the vertical *component* of an objet launched at an angle which is
y = vy * t + .5 * g * t^2.
If I have inserted foot in mouth please let me know. But I believe this is
correct. Oh also go back and take a look at your first equation and
my equation the only diffs are that I take into acount that I don't start
on 0,0 coords but 50,300 coords other than that they are almost identical.
You have reproduced my chicken scratch.
Any one feel free to jump in please. Gee I didn't know my foot stank that
bad.
