Right, I'm not sure if you mean you need help writing a script, or you need help animating the script, but I will do my best to cover both...
I've written a short script in the same format I write all of mine. And next to it, I've put coloured sentences describing what to do on each part of the script.
Short script:
INT. CAFE - DAY This is the name of your set, and the lighting.]
BILL and JOE are conversing at a table. The two figures are at a table prop, animate their dialogue with hand and body movements.]
CAMERA SWITCHES FROM BILL TO JOE AS THEY SPEAK The camera should point at each one's face as they speak.]
The following is a basic dialogue conversation, what you need to do here has been covered.]
BILL
I don't know what to do, Joe, if I don't pay up soon, we'll be out of our house and on to the street.
JOE
Is it that bad?! Can't he delay the payment for you? Sure ly he can see that you literally can't pay up!
BILL
He doesn't care, he just wants his money.
JOE
Well then you need to find a way of making money.. Do you have any valuables that you wouldn't mind selling?
BILL
No, we already tried that.
JOE
Then, perhaps a way of saving money? Are you paying for anything monthly that you could do without?
BILL
Nope, we only have the bare essentials... I wouldn't come to you if I had any other way.
JOE
Don't worry, my friend, we'll think of something.
BILL
Let's go outside, I need some air.
JOE and BILL STAND UP and leave the table. I put mian actions in CAPS so you can see them clearer. This means that you will animate both of the figures standing up from the table, and walking away using a basic walk cycle.]
EXT. STREET - DAY Name of the set, lighting.]
JOE is staring at a poster of a golfing tournament which is hanging on a lamp-post. Describes the position of the JOE character. Most likely standing still, with his head back looking up at a poster on a lamp-post prop.]
BILL
I don't know what I'm gonna do...
JOE
Hang on Bill, I think I have an idea....
THE END Self-explanatory.]
So, I hope that's helped a little bit...
I'll try and help you as best I can if not.
