I'll try to explain as best I can. Maybe I can word this in a way that best resembles a word problem even, making it more relatable to the more math-savvy Construct users here.
I have three objects, and every single one is imperative to my idea. I have a player object, an arm, and a hand. This employs my grappling idea. The character reaches his hand forward to grab onto grapple points. To do this, a hand bullet object is shot from the player object. But we can't just have a floating hand, right? I was going to have a third object, an arm, but I have no idea how to make it stretch out between the player and hand object.
How can I make the arm object's width stretch out between these two moving objects? I can't figure this out for the life of me, and I can't just try figuring it out based on .X positions since the player could fire off the hand object in mid-fall or something. (Not that I ever figured out how to get it to work with just .X positions anyway shooting it out straight horizontally.)
I'm guessing this problem will have to do with cos, or... cosine or... whatever... I have no idea. I hope I explained this well enough for anyone reading this to understand what I'm doing. ^^;
