[AI movement] Jumping using movegravity()

[randall]

I have also wrote a sqrt function, its accurate to 6 decimals:

		sqrt( b )
{
    a = 0;
    for ( i = 1; i <= 1000000; i *= 10 )
    {
        while ( a * a <= b )
            a += (1 / i);

        if ( a * a > b )
            a -= (1 / i);
    }

    return a;
} 
	

To increase the accuracy write a bigger number in 'for' cycle.

And an other mathematical function:

		vectorCross(vec1, vec2)
{
    result =
    (vec1[1]*vec2[2] - vec2[1]*vec1[2]) -
    (vec1[0]*vec2[2] - vec2[0]*vec1[2]) +
    (vec1[0]*vec2[1] - vec2[0]*vec1[1]);

    return result;
}

I have also wrote a sqrt function...

my one:

		sqrt( x )
{
    y = x;

    for( z = x *0.25 ; abs( z - y ) >= 0.001 ; y = ( z + ( x / z ) ) * 0.5 )
    {
        z = y;
    }

    return y;
}
