a gml implmentation of the javelin game (see the games link)

objJavelin Create

x = 50;
y = 500;
rspeed = -2; //rotation speed
aim_direction = -90;
thrown = false;

objJavelin Step

//*** KEYBOARD PRESS ONCE TO THROW: ***
if keyboard_check(vk_space) and not thrown {
    thrown = true;
    gravity = 0.3;
    speed = irandom_range(5,15);
    direction = irandom_range(25,65);
    aim_direction = image_angle + 90;
}

//*** IF JAVELIN IS IN AIR, ROTATE: ***
if (thrown == true)
{
    image_angle += sin(degtorad(aim_direction - image_angle))*rspeed;
}

//*** IF LANDED, RESET: ***
if (y > room_height) { 
    thrown = false;
    gravity = 0;
    speed = 0;
    x = 50;
    y = 500;
    image_angle = 0;
}
