How do I make a platformer style level?

[Tombo]

Hey guys - new to the forums.

How would I go about making a platformer game like LISA? - I'm comfortable with battles, messages, sfx & sprites etc.

The main part I am struggling with is getting the playable character to walk against blank 'A' tiles.

As below you can see I've been looking at this tutorial, I can't understand how the player is walking on top of blank tiles - as you can see the parallax background?

Edit: Also I am using VX Ace.

-Thanks

You place a blank tile on top of the parallax marked with O passability where you want the sprite to walk.

Ahh thank you, such an easy fix - you've saved me a lot of frustration.

Cheers!
