gun swirl

[frodo]

I have a man with a 360 degree gun animation. His gun always points towards the mouse. Right now, if you have the mouse on the right side of the man, and you quickly put the mouse on the left side of him, he just changes degree from 0 to 180. I want him to swirl his gun around in a full loop to the direction of my mouse. would it be something with "vectoradd"?
Thanks

You mean there is a bias in the direction that the actor wants to turn?

Try this in the Draw Actor event:

Code: Select all

//Create some vars
double mouseangle, weight;
int newAnimpos;

//Get current angle between mouse and the actor
mouseangle = direction(xscreen, yscreen, xmouse, ymouse);

//Calculate the new frame based on angle
newAnimpos = (mouseangle/360.0)*(nframes-1);

//Set the weight of motion
weight = 20;

//Calculate the lazy frame position
//Create anim as real, actor variable in the variables button
//Need this because animpos is integer and don hold the fractional changes

anim = (newAnimpos + (weight - 1)*anim)/weight;
animpos = anim;

Makslane, that dosn't work

What's the problem?

Put this in global code:

Code: Select all

double getangle(double A, double B)
{
    double result;
 
    result = B - A;
    if(result>180)
    {
        result = 360 - result;
        result *= -1;
    }
    else if (result < -180)
    {
        result = 360 + result;
    }
    return result;
}




double ReDir(double A, double B, double mag)
{
   double ang = getangle(A, B);
    if(abs(mag)<=abs(ang))
    {
        if(ang>0)
        {
            return A + mag;
        }
        else if (ang < 0)
        {
            return A - mag;
        }
        else
        {
            return 0;
        }
    }
    else
    {
        return B;
    }
}

Now, in draw actor, instead of saying faceangle = todir (where faceangle is the angle the animpos represents and todir is the direction to the mouse), say

Code: Select all

faceangle = ReDir(faceangle, todir, n);

where n is the number of degrees to move each frame.

dillodude, How do you use global code? when I get done puting in my code, what do I do next? If I press close, it asks me if I realy want to close it. Do I have to save it before closing it out? Thanks

[DilloDude]

There is a bar at the bottom of the window, that says 'name'. put a name int it (like functions) and click 'add'. That way you can store things in separate blocks of code. You might want things like variables, angle functions, other functions etc.

[frodo]

in draw actor, it dosn't reconize "todir", "faceangle", and "n"

He forgot to tell you that you need to create some variables. just click the varibles button a the bottom of the script editor. the variables dont have to be exactly what he said, that was just an example

[frodo]

It's just the same as before...

I put this in draw actor:

Code: Select all

int gunangle=man.animpos/man.nframes;
angle=direction(xscreen,yscreen,xmouse,ymouse);
if(gunangle != angle)ChangeAnimationDirection("Event Actor", FORWARD);
if(gunangle=angle)ChangeAnimationDirection("Event Actor", STOPPED);

i didn't work. is there reason why this wouldn't work?

[frodo]

doesn't "=!" mean does not equal?
That's why I did:

Code: Select all

if(gunangle =! angle)ChangeAnimationDirection("Event Actor", FORWARD);

[Fuzzy]

doesn't "=!" mean does not equal?
That's why I did:

Code: Select all

if(gunangle =! angle)ChangeAnimationDirection("Event Actor", FORWARD);

Be careful with that. you want to use != rather than =!. I think you can also use <>.

[frodo]

my idea still doesn't work.
