I have a fixed startpoint A at x,y and a dynamic destination at B x,y, by selection of mouse/touch.
I am looking for an approach other then physics to make an object follow a parabolic leaps from a to b in a isometric like scenarion.
It does not have to be precise, or a perfect arch, its for a bit of eye candy so it needs to be light and perhaaps lerped or something.
I'd like to do this without plugins.
Right now I use a combination of a fixed 270 ddegree impule combined with an angluard impulse with some distance math. It works semi, though, its not perfect, far from.
Another approach I used was with a bullet and some gravity, but I cant make out the formula needed to have it target switch to another B point.
the best so far was with the physics ...but its also in accurate, if you have a better suggestion then the following:
targetx,y is start point, countries x,y is point b

If you see room for improvement or have a better approach, I'd be gratefull :)
In short: how do I make an arch like effect between 2 points on an x,y grid.
