/prog/ - The Best Jump Algorithm?

Name: Anonymous 2012-03-12 10:35

Who's up for a bit of challenge or provide some tips or better code?
I'm having trouble with the math side of doing jumps on the game I'm making.
Can someone please help me out for a while?
My character's jump looks weird, it looks pointy.
There's code here http://codepad.org/SXH4ydz8 where we can start.
There are constraints there.

jnz is the best jump.

Make a proper Physics simulation and just give your Entity an upward force of X newtons which will cause it to rise into the air and then eventually fall back in a nice smooth pattern due to gravity.

upward force of X newtons
upward velocity of X [m/s] *

Wrong. Realistic physics in a video game are shit and eat a lot of processing power.

Simple Force simulation with gravity do not eat up a lot of processing power.

OP here

I thought of adding fall velocity to jumpspeed (now tempspeed)
then let it jump with tempspeed then decrease tempspeed by velocity*deltaTime

But that's just me saying, dunno better code from what I can think...

Forget it, white people can't jump.

On a related topic, does anyone have the exact algorithm used in Super Mario Bros?

It is np-hard OP, don't bother

I've seen the original source and they just implemented a basic physics engine: http://en.wikipedia.org/wiki/Standard_Model

The jumping force, air resistance, gravity, etc, just came about naturally as a result. It's all about emergence bro.

This is why I love you, /prog/.
