RPG Walking Sideways From Mouse Direction

Hi, I'm working on an RPG game, i have the player point at the mouse forever, and move forward and away from the mouse, but how do I have it move sideways (move left and right but not just the x axis, y axis should also be involved).

Re: RPG Walking Sideways From Mouse Direction

Okay, here's part of it:

if (key [left arrow v] pressed?)
 change x by (([sin v] of (direction)) * [movement])
 change y by (([cos v] of (direction)) * [movement])
end
if (key [right arrow v] pressed?)
 change x by ((0) - (([sin v] of (direction)) * [movement]))
 change y by ((0) - (([cos v] of (direction)) * [movement]))
end

I'm pretty sure I got this much correct, though something might have gone awry.

Anyway, I hope that this helps!

Thanks! I'll try it, but i'm confused by what to put for movement, does 1 = 1 step, or mushc smaller or larger.

Correct, 1 would equal 1 step, and now you just need to replace movement with how many steps you want to move left and right.

Oh, and I'm not sure if I've said this to you yet, but hello and welcome to Scratch!

By the way, do you happen to know how to move forward and backward?

So I tried this code, it is the code for moving forward and backwards XD, do you know how to do left and right?

Ohhh… My mistake.  tongue

Anyway, I fixed the code ^^.

Edit: Fixed again.
