In my volleyball game I am making an AI system, but I can't get it to work correctly. I have the part to make it move left and right to hit the ball, but I can't get it to jump at the ball. Here is the code I am currently using in the Step event.

[codebox]{
if ball.x > room_width/2 {
if ball.x < x
{
x -= 2;
}
if ball.y >= x
{
x+=2;
}
{
if ball.y < y
{
vspeed-=8
}
}
}
}[/codebox]


I also have a gravity code in the Step event. I know the problem with this code, it just keeps telling it to go higher and higher because the ball is close to it, but how do I fix it?


--Thanks

The problem is in

if ball.y < y
{
vspeed-=8
}

This makes the vspeed decrease 8 each step, which, unless you have some very high gravity, will "float off." I suggest you change it with something like this (assuming you use some sort of object for the floor):

if(ball.y < y && !position_empty(x,y+1))vspeed-=8;
