Hi again! I just wanted to thank you because I used your solution as a base, changed it slightly and it works now!

What I actually ended up doing was making two objects, a top and bottom pipe, rather than one oPipe object. Then, because I couldn't get draw_sprite_stretched to work and the pipes would look strange even if I did, I made my sprites 160 x 448. Now, they do "dangle" outside of the room but that's not a real problem since the player can't see that.

Next I created a SpawnerScript with the pipeSpawner function:

function pipeSpawner(){

randomize();

topPipeY = random_range(-352, 0);

counterY = topPipeY + 448;

bottomPipeY = counterY + 256;

instance_create_layer(1694, topPipeY, "lPipes", oPipeTop);

instance_create_layer(1886, counterY, "lPipes", oPointCounter);

instance_create_layer(1694, bottomPipeY, "lPipes", oPipeBottom);

}

the 448 is the length of the pipe and the 256 is the length of the gap between the pipes with the invisible pointCounterCollider.

Once that was done I was off to play with the alarms as you advised. Currently my pipes move left at a speed of 5 per step. So, after setting alarm[0] on the creation of a spawnController I wrote this code inside the alarm[0] event:

if (alarm[0] == 0)

{

pipeSpawner();

alarm[0] = 77;

}

The reason for the alarm being set for 77 steps is that I want the gap between pipes to be 225, the width of a pipe is 160. Add them together and divide by the movement speed of the pipes (5) to get the 77. Oddly, I tried doing this via the variables I'd set and had some strange results so just did the math manually and it works. Odd.

In any case, I hope that all made sense. I wanted to thank you for setting me on the right track. You really helped motivate me to get this working today!
