2-d mario movement script

[fadark]

can someone make/find me a script that makes the movment like it's in the super mario games for the gameboy?

some ideas on how to make this are:
-make it so if a terrain tag is 1, make it so you cant jump on it.

-make your movment speed 3 when you start running but slowly get to the max (4). increase speed in increments of 0.2

-depending on how fast you are running, decides how far you will jump.


thanks-a-ton in advance if you help!
