Custom arc movement with slight acceleration.

in Working with GS (Mac)
Hi there!

Once again (hopefully the last one) I am forced to humbly ask you for your help.


I want to make custom arc movement - it is going to be a planet that goes on the specific arc. I would love to have there an attribute that can vary the arc value, as I want my actors to be recycled and to shoot at.

I tried to make velocity + acceleration but I was not satisfied with the result really.

    Hi! Thank you for your comment, but it is not really what I have I mind.

    I wanted to achieve effect of a falling planet or something like that and I need equation for that arc.

    I tried constrain pos x and pos y to sin/cos, but I can't figure it out to work properly.

    @rthurman I was thinking earlier I should tag you in this thread as you are the vector math king, ^:)^

    @FryingBaconStudios -- actually I am terrible at math. I never learned (or at least retained) my math facts. I still count on my fingers! I have to recalculate every multiplication I make (because I don't have multiplication tables memorized).

    The truth is, I am just plain lazy and find it much easier to have GS do all the calculating for me. Mostly I just know how to search the interwebs for the kind of math formulas that come up in games. I would say my main skill is being good at google search (and sometimes recognizing the right formula when I see it).

    Same here, terrible at maths, count on my fingers and recalculate every multiplication I make (and for the same reasons) and I get GS to work stuff out for me, I just throw a load of stuff at GS and see if it kinda' works, if something is going backwards I throw a 'minus' in there, if it's too slow I throw a 'multiply' in there somewhere, I never work anything out in advance, just kind of 'sketch' it out and then repair it until it works, then tidy it up once I know how it works.

    I'm sure a real mathematician would be appalled !
