Sorry for not being too much present here...
for apologize I want to show you an idea I had about the similarities between Coroutines in lua and gears.
then, on the base of circle, I have programmed a physical model which can recreate the gear movement, like a clock in fact ( I think I'll need objects in the further version).
The code above is only the gear creating function, please try it and tell me what you think about that idea.
require("draw")
showgraph(1)
draw.onbuffer(1)
pi = 3.141592654
function rouage ( x,y,r,t,pas,o,p,a )
e = 0
for i=t, 2*pi+pas , pas do
e = e+1
if e%2 == 0 then
r = r+a
draw.line ( x+(r-a)*math.cos(i), y+(r-a)*math.sin(i), x+r*math.cos(i), y+r*math.sin(i) )
else
r = r-a
draw.line ( x+(r+a)*math.cos(i), y+(r+a)*math.sin(i), x+r*math.cos(i), y+r*math.sin(i) )
end
draw.line ( x+r*math.cos(i), y+r*math.sin(i), x+r*math.cos(i+pas), y+r*math.sin(i+pas) )
r = r - pas*o
end
end
roue1 = coroutine.create (
function ()
pa = pi/5
while true do
for j=0, 2*pa, 0.03*pi do
rouage ( 75,100,50,j,pa,0,1,10)
coroutine.yield ()
end
end
end )
while not testkey(K_EXE) do
draw.clear ()
coroutine.resume ( roue1 )
draw.update ()
endHope you'll enjoy It
See ya later
