How do I search through array at y1 to get x

I have a 2d array where each X represents a location. The y value for that x contains the name, location, and other game values. I am at a spot where I need to search through all the values at y1 so I can figure out which x it is on. I have not been able to figure out how to do this in the event sheet. Any assistance is really appreciated.

You use a for loop for this.

Look here at loops: https://www.scirra.com/manual/124/system-conditions

In the for loop you access your Array at x, which you iterate and y1 (fixed).

Yes, I have tried this, though I don't know how to keep y1 fixed.

I tried the following, and don't know how to only check values on y1.

Use System.For

A FOR Loop is something different than a FOREACH Loop

Use System.For

Yes, thank you that is much more how I think of iterating over arrays. Good to see how to do it in this paradigm. Working as expected now. I appreciate both of your time for responding to my question.
