Hi guys.
I know this post has only just been resurrected but is anyone still stuck on getting the burning ship working in FractInt?
Only reason I ask is that I've just spent two minutes writing this and I'm happy to share the code if anyone's stuck. I've also created a slight variant of the fractal too, which I've named KungFuPanda. You'll see why if you give it a try.
Anyhow, here's the code:
burningship {
; SMF to demonstrate how to do it.
if (ismand)
p = 0-pixel
z = p
else
p = 0-p1
z = 0-pixel
endif:
z = abs(z)
z = z * z + p
|z| < 4
}
kungfupanda {
; burning ship variant
; abs(z*z) in place of abs(z).
if (ismand)
p = 0-pixel
z = p
else
p = 0-p1
z = 0-pixel
endif:
z = abs(z*z)
z = z * z + p
|z| < 4
}
What seemed to be missing in the early replies to this thread was the bailout condition at the bottom (the last line essentially). Unlike the colon : which simply separates the initialisation from the per iteration code, there's nothing separating the bailout from the rest of the code. It takes some getting used to, but can give undesired effects if you forget about it.
In case you were wondering about the if (ismand) section, this allows the user to display julias too. Essentially, you press space bar. This brings up a crosshair, which you move around on the screen (hold down control if you want it to move faster). When you are happy with your coordinates, press space again and you will get the julia of the location under the crosshair. To return to the non julia variant press space once again. The status of the ismand flag and the location of the julia are saved in the parameters (and embedded within any saved .gif file), but if you want to set one manually or see what it is set to, press z while displaying the fractal to go to the parameters screen.
Here's the KungFuPanda variant I've found:
Any problems, let me know as I've been using FractInt for some time.
