 Not available yet, but it is coming eventually via WebGL according to the roadmap.

 HTML5 is only compatible with modern browsers (IE 9 or newer). It also doesn't go well with search engines (google), because your website is almost entirely inside javascript. An alternative is to make various parts of the website with HTML5 that can be loaded and displayed wherever you want.

 

It rotates around the sprites origin

ok so how should i do this? i tried centering it and it still doesnt work

 

 

The sprite should be facing right, and the origin should be at the spot you want it to rotate around.

 From the error message, it looks like you haven't defined the variable tFOV. Initialize it in the create event or something.

 This type of question belongs in the Questions and Answers forum.

As for your question, physics_apply_force() may be what you're looking for. However that only affects a point in the room, so you may need to loop through all physics objects and apply a force base on distance.

with(obj){
     var dir = point_direction(x, y, other.x, other.y);
     var dist = point_distance(x, y, other.x, other.y);
     if(dist < 100){//change 100 to the radius of effect that you want
         physics_apply_local_force(x, y, lengthdir_x(dir, 5), lengthdir_y(dir, 5));
     }
}

Note: the code is untested.
