Scratch

Velocity is actually pretty simple, in concept.    All you need is a velocity variable for each axis, which is increased or decreased based on key presses. Then you just change the x/y position by the corresponding velocity variable. A simple x velocity script might look like this:

When green flag clicked
Forever
    If <key right arrow pressed>
        Change x velocity by 2
    If <key left arrow pressed>
        Change x velocity by -2
    Change x by x velocity

You can add a lot to it, like adding friction that makes you slowly slow down, changing how quickly the velocity changes, and adding a limit to how fast you can go, but that's a basic velocity script. I hope that helps you understand!

"BIG PROJECT" forum? What do you mean? Oh, and "Expert Scratcher"? boy, I'm flattered :P

Umm, this is about helping me but I guess I could help you? Okay you see on the top where there is a blue line and you can move it so it changes direction? Well there is an x position and y position. Check the x position. Then take out your script saying
When Flag clicked forever if touching blue then move -15 steps, no that will just make it move backwards! Take that script out. Then get a
When Flag clicked
forever
if sensing x position of Sprite number operators = the x position
then set x to x position of Sprite number and y position of sprite number.

Next time post your need for help in a different topic  .

Oh, I mean is go to Collaboration (way bottom) and there should be a topic titled, 'Big Project'. I need some Scratchers who are very experienced with Scratch and can help out. I would like to have some help with

scrollx
designing
scripting for new places
and much more. So please go there.

Oh and for the experienced Scratchers? You are one! I am a newbie scratcher and probably have 0 skill at this programming software. I need your help and much others, can you tell your friends if they have been around Scratch for QUITE some time, and ask them to go to forums -->  way bottom of page -->  Collaboration --> Big Project. If you do I will be very grateful!

Oh, I see. I'll gladly help out in couple days once I get more time. (Long story)

XD a couple days?

Oops. XD Sorry. I guess this died after you didn't respond. Is the thread you're talking about still up, or have you solved your problems?

Oh no it was sort of like a joke. I was browsing through my old topics, I can maybe fix this problem, I am still not this professional, but I have improved greatly. To see check these two projects and look at the differences:

Good one: http://scratch.mit.edu/projects/Thescratch3/1997263

Old one: http://scratch.mit.edu/projects/Thescratch3/1873764

Wow, great improvement!
