Scratch

I think that they should team up rather than fight each other. But it is up to you on what you want to do.

Personally, I think you're getting ahead of yourself. Isn't it more like "Once I learn Python..." unless you're already pretty good at it

This. I don't think you'll be able to just dive into doing complex animations as soon as you encounter Flash. Flash is a much more advanced system than Scratch, and harder to master too. I don't actually work with Flash myself, but I've learnt to read ActionScript when I was translating these tutorials into Scratch, which later became my SpRiTeD 3D Projection Engine.

Here is an example of some ActionScript code, which was later converted into my Rotating 3D Cube project.

...
Transform3DPointsTo2DPoints = function(points, axisRotations){
    var TransformedPointsArray = [];
    var sx = Math.sin(axisRotations.x);
    var cx = Math.cos(axisRotations.x);
    var sy = Math.sin(axisRotations.y);
    var cy = Math.cos(axisRotations.y);
    var sz = Math.sin(axisRotations.z);
    var cz = Math.cos(axisRotations.z);
    var x,y,z, xy,xz, yx,yz, zx,zy, scaleFactor;

    var i = points.length;
    while (i--){
        x = points[i].x;
        y = points[i].y;
        z = points[i].z;

        // rotation around x
        xy = cx*y - sx*z;
        xz = sx*y + cx*z;
        // rotation around y
        yz = cy*xz - sy*x;
        yx = sy*xz + cy*x;
        // rotation around z
        zx = cz*yx - sz*xy;
        zy = sz*yx + cz*xy;
        
        scaleFactor = focalLength/(focalLength + yz);
        x = zx*scaleFactor;
        y = zy*scaleFactor;
        z = yz;

        TransformedPointsArray[i] = make2DPoint(x, y, -z, scaleFactor);
    }
    return TransformedPointsArray;
};
...
rotateCube = function(){
    cubeAxisRotations.y -= this._xmouse/3000;
    cubeAxisRotations.x += this._ymouse/3000;
    var screenPoints = Transform3DPointsTo2DPoints(pointsArray, cubeAxisRotations);
    for (i=0; i < pointsArray.length; i++){
        currBalloon = this["balloon"+i];
        currBalloon._x = screenPoints[i].x;
        currBalloon._y = screenPoints[i].y;
        currBalloon._xscale = currBalloon._yscale = 100 * screenPoints[i].scaleRatio;
        currBalloon.swapDepths(screenPoints[i].depth);
    }
};
theScene.onEnterFrame = rotateCube;

I've left out a lot of the supporting functions, but if you haven't learnt Flash yet, this code will look extremely confusing. I'm not trying to discourage you from learning Flash, but I think you should learn how it works and how to program in ActionScript before trying to make complex animations/fight scenes.

Hi i'm andresmh this is to unscratchy for me i'll have to take down this tread

Don't pretend to be a member of the Scratch Team at MIT, especially when we can see your name and your huge banner

No, you arn't Andremsh, Stop impersonating him, it could get you kicked off. 2ndly, Can you please make your banner smaller!!!!!

It was a joke of coruse

sorry if you didnt like that

Do you even know how to use flash yet? Learn flash first, then plan out what you will make.

Whoops, I didn't read the part about the post being Flash. Fixed.
