GML Visual Spawn objects from middle top of a object

[tidlon]

Hi I am kind of new to programming and I am trying to make cubes spawn randomly from center top of an object/sprite, so this is what I currently have...

and here is the code for the object that I want to spawn...

but it end up spawning the cubes a bit to the right of the object and not in the middle of the object as I want it to... like this

please help.. how do I make it so the cubes spawn in the middle of the actual object (the object is the grid in the middle)

Just uncheck the relative position of the X on the create event.

You are spawning over a grid, so set the coordinates to the grid. Set the x coordinate to

(width of the lines + 158) * irandom(4)


...edit: Wait, why is your spawning object using a sprite 299 pixels wide and the SynthNote is 158 pixels wide?Of you have multiple spawning objects, then why use random x coordinates?

Also, random() uses decimals. You almost never need or even want decimals, so use irandom().

Thanks for the help, the problem was the DnD create instance, once I used GML instead it worked perfectly, it now spawns from the exact middle of the object which I wanted it to, seems like its a bug with the DnD create instance..

It's probably because you had relative checked. Also, I wasn't paying attention when I commented last time, but the value you put in y is just the object index. so the object index relative to the y-coordinate is slightly off-center because the object index is greater than 0 apparently. using the D&D, if you had just put 0 for y, you should have been fine.
