How to make gravity that works if you move too

laduester42

Hey guys,

in a new game I'm working on, it is similar to the game Red Ball. I have arrows that lead you in the direction you want with up as a jump. I have under all the arrows to push down (accelerate) to create a gravity, but when you press up and right, it makes more of a triangular jump than a smooth circular jump. Also, if I fall off a platform and still hold on to the arrows, I don't fall immediately like in Red Ball, but I slowly fall in the direction I am pressing. This gravity is stopping me from releasing the app. Without this, the game looks very amateur and that's not good. If any of you know how to make this work, that would be awesome. It seems on Youtube, no one made a video about this; just to fall.

Thanks,
LaDuester

Instead of using the move or accelerate behavior, have it so that when right is pressed, change attribute self.Motion.Linear Velocity.X to 300
and for up change attribute self.Motion.Linear Velocity.Y to 300 For Left instead of 300 for the X, have -300.

it's a little better, but still kind of has a triangular jump. as for my second problem, same thing: little better. Any suggestions?

actually, i just tested my second problem again, and it's worse

its because you have a dual acceleration in two different directions.
Make a true/false scenario where if.game.attribute.up is true = accelerate up
otherwise accelerate down

That works, but do you know how to make a circular jump when you press up and right instead of a triangular jump. If you can, that would be great.

use the sin function?? might need to check with an expert on that. i have not use sin cos function personally.
