You probably heard this before, but i have a problem with getting my tanks to shoot at each other at an angle so that the missile curves while traveling towards the other player. So far I have 4 variables: power, angle, playerpositionX, and playerpositionY. Can som1 help me with making a formula that i can use to get my tanks to shoot properly. I'd also very much appreciate it if you could also code it for me so that i can change it into my variables and have it working. Just a simple demo is all I need. Thanks again. |

This is against forum rules. To get the trajectories, you will need to keep track of vertical + horizontal velocities and acceleration. Just like in a typical "throw object from a cliff" type of problems from the Physics class. |

lmao, those kind of questions were fun . Nitler, this isn't a forum where you get answers. Learn how to do things yourself or ask for help instead. No one here will/is allowed to simply post code for you so you can take it and manipulate it for your own usage instead... If you give a man a fish, he has food for a day. If you teach him how to fish, he has food for life. Same idea... |

It's really not that hard. Once you get the missile to go at the desired angle, then y component of the speed of the missile needs to decrease at a constant rate. |

Currently this is what i have, and I have 2 little problems with what i have here: 1. If i set angle to 2, or 3 and so on, the missile isnt drawn 2. if i set angle to 45, notice the missile doesn't start at the exact angle of 45 please help, and show where my mistakes are so i can fix them!

are you sure that cos/sin operate on degrees, not radians? |

try cosd and sind instead. they use degrees, not radians |
