This is not good AI at all. There are way too many objects, also.

Decent pong ai:

if obj_ball.x > room_height/2
move_towards_point(x,obj_ball.y,5)

That's it.

3/10 for effort.

hey you guys its reaching its target audience of game maker noobs i remember the first time i ever used GM i would've killed for an example like this.

SUCKS
1/10

3/10 because I like the gray image on this page...

BAAAAAAD.

Lmao, sorry to say this man, but GTVG AI is probably the best lawlers. If you used his idea and replace the 5 with a variable so you can adjust difficulty of the pong ai, It would've been alot better and superior in simplicity.

And Wow, enough objects man, your making the game lag like hell.

Lets just say its bad...

just one thing.the p2 bat just jump to a given position.Use move towards point with x - self.x and y - BallFollowAI.y .For the speed use 5.And finally just put some variable for the difficulty.For the test chance use some variable.The higher the number the difficulty is reduced.It's not the best solution but...
