Scripting Sprites || URGENT HELP

I am pretty new to the scripting world when it comes to making games, I was wondering if anyone would be willing to assist me regularly with any issues that I may have along the way, I have some idea of how scripting works when it comes to 3D (Which I only practically know how to build a level where the player is ball)

So... I'm not to advanced, I know how to make and rig sprites and create collisions and stuff like that, but I have absolutely no clue how to script my characters to get them moving.

So my character only consists of 4 parts, I already know how to animate him... But what is the process to linking the script with his animations, this part I find very confusing. He has two legs, his head and the main body section.

Any help would be really appreciated. Thankyou! :D
