Help lobbing a projectile

[mobichan]

I am trying to make a side scroller where the player controls a ship and a cursor and can lob projectiles at the cursor's position from the ship. The problem is I can't figure out how to make the projectile pass through the cursor's position. I need the lobbed object to arc upward and then downward through the cursor's position (stored position where the cursor was when the projectile was fired). I am really bad at understanding the math involved and can't figure out a good way of faking this. Can anyone offer an example or a good place to look for info?

Thanks in advance,

Mobichan

You need to learn Bezier curves.

So, I originally tried using Move By bezier to do this, but the problem is I don't want the projectile to stop when it reaches the target point. I want it to continue to fall offscreen. So this means the target point is actually on the curve, not the end point of the curve.

Any idea how I would do this?

Wow, now that I have gone through the article and gotten it working, I guess the answer is to just keep increasing the t variable until the object is offscreen. Beziers are really not that hard after all.

That works, but using pinball movement, and doing:
(Example)
Player presses space bar - create object (diamond-like thing with the star) at 0,0 from player's ship AND add set the projectile's direction to (select your direction). Then tinker with the gravity. This should work, it has worked form me. The other way sounds a bit too complicated.

I just put an example of that on my website. Shoot Up Example.

Thanks for the suggestions guys, but Beziers did the trick and they are dead on accurate.
