Make the A.I Paddle follow the ball

-----------------------------------

What is it you are trying to achieve?
I aim to make the A.I Paddle follow the ball so that it never goes below it.

What is the problem you are having?
I am unable to make the paddle move first of all but i think this is just the same step as making it follow the ball so i want to make it follow the ball.


Describe what you have tried to solve this problem
making if statements for if the paddle is greater than this location paddle -= 10 and if it is less than this location it goes += 10, it doesnt move, it stays still

Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)


if ball_y2 >= maxy - 50 then
            ball_directiony2 *= -1
        end if
        if ball_x2 >= maxx div 2 + 40 then
            ball_directionx2 *= -1
        end if
        if ball_x2  x1_1 then
            x2_2 += 10
            x1_1 += 10
        elsif ball_y2 < x1_1 then
            x2_2 -= 10
            x1_1 -= 10
        end if 

insectoid i used your code but for some reason with these boundaries of my paddle 

if x2_2 > maxx - 31 and x1_1 < maxx - 131 then
            x1_1 -= 10
            x2_2 -= 10
        elsif x2_2 < maxx div 2 + 131 and x1_1 > maxx div 2
+ 31 then
            x1_1 += 10
            x2_2 += 10
        end if

the paddle goes to the left and then even when the ball moves right the paddle trys to move right but stays on the left.

Is it intended that you're comparing the y-coordinate of the ball with the x coordinate of the paddle?

The paddle doesn't even need an X variable, since it only goes up and down.

Then why are you comparing the y values of the paddle?

RE:Make the A.I Paddle follow the ball

-----------------------------------

X1-1 is the first x co'ord of the paddle
X2-2 is the second x co'ord of the paddle
Ball-y2 is the y co'ord of the a.i ball

Nowhere in the code does it say the y co'ord of the paddle

X1-1 is where the drawfill box starts
X2-2 is where it ends

How do i get my paddle to follow the ball properly, the code i prompted it with worked but when my code starts the a.i paddle goes to the left and trys to go right but a force blocks it and it doesnt. Would you feel more comfortable with my question if i provided the code for my actual game?

Need Code: Yes.

What he means is why are you comparing the paddle.pos.x to ball.pos.y? The relation is on the x-axis, so you'd be comparing both x values. This is a one dimensional problem.
