so for example i have this:

no problem using lineto.

but, what if i want to do this ?


i´m simply not sure about the maths here. anyone could guide me?
i always have source and target coordinates but how would i go about "dividing" this
line into lets say 8 [img]lineto[/img]´s with slight random variations but still point to the target?

anybody could help me? would be much appreciated thanks!!

Hmm, thats a hard one.

You can always try:

Code: Select all

for(i=0;i<(distance(x,y,target.x,target.y)/2);i++) {
moveto(x, y);
lineto(i, i);
lineto(i, i);
lineto(target.x, target.y);
}


Untested, but might create a stagger in th emiddle.


There is another method but it's a long rout to take.

Thank you Will give it a try!

Here's my version

Code: Select all

int i,rx,ry;
int Crack=25,Force=25;
setpen(0,127,255,0,3);
moveto(0,0);
for(i=0;i<Crack;i++)
{
    rx=(rand(2)-1)*((float)i/Crack)*Force;
    ry=(rand(2)-1)*((float)i/Crack)*Force;
    lineto(((float)i/Crack)*width+rx,((float)i/Crack)*height+ry);
}

variable Crack is how many segment should crack and Force is the intensity of the cracking.
note, the cracking intensity is graduate, so it starts smoothly to more and more

exemple that follows the mouse (put in draw actor)

Code: Select all

int i,rx,ry;
int Crack=25,Force=25;
erase(0,0,0,1);
setpen(0,127,255,0,3);
moveto(320,240);
for(i=0;i<Crack;i++)
{
    rx=(rand(2)-1)*((float)i/Crack)*Force;
    ry=(rand(2)-1)*((float)i/Crack)*Force;
    lineto((((float)i/Crack)*(xmouse-320)+rx)+320,(((float)i/Crack)*(ymouse-240)+ry)+240);
}

or

Code: Select all

int i,rx,ry;
int Crack=10,Force=10;
erase(0,0,0,1);
setpen(0,127,255,0,3);
moveto(320,240);
for(i=0;i<Crack;i++)
{
    rx=(rand(2)-1)*min(1,((float)i/Crack)*3)*Force;
    ry=(rand(2)-1)*min(1,((float)i/Crack)*3)*Force;
    lineto((((float)i/Crack)*(xmouse-320)+rx)+320,(((float)i/Crack)*(ymouse-240)+ry)+240);
}

amazing, thanks very much!
thank you both
