Edit: The code I wrote is complicated in a stupid way so I have attached a better version that also fire two bullets in a mirrored pattern.

| Post subject: | Help with sine waves |
I want to make a projectile move along a path using sine. But to tell the truth, I am really not sure how to do this. I would imagine using the velocity with the sine function and all that. Essentially i want to have a projectile move along a wavy path(sine). It has to work regardless what angle the projectile is fired.(fancy looking projectile yay) any help will be wonderful. thank you. |

Unfortunately I can't give you the complex 50 line math blah, but I can suggest using a timer, sine function on it, and self.Vel.Perpendicular. |

Shook's Pack O' Mods has a Sine wave gun. But it only shoots horizontally. Aiming higher/lower changes the speed. You could try looking at the code for that, and cannibalising it? I'd upload the .lua file, but I'm not sure what the rules are on posting other people's code. |

To make a true sine wave in all directions, you'd have to have the projectile figure out what direction it was aimed at and instead of linking the X or Y coordinate to the sine function, link the sine function to some scalar perpendicular to the particle's motion vector. I'm not that great with math, but it should be doable if you have a good knowledge of trig and coordinate math... |
