AEE - Second Parallax Layer

[Crazyninjaguy 9]

Introduction

 

This is a complete rewrite of my older 'Second Parallax Layer' script to make it more performance friendly, and bug free.

If you set a new map up in the script to have two parallax layers, then it will take the filename of the first parallax and add "_layer2" to the end, so for example, if you set "BlueSky" as your parallax, the layer 2 filename would be "BlueSky_layer2".

If you want to display a parallax the default way, just don't set it up in the script.

I just learned about parallaxing like this. you have great timing.

[shaz 77]

Thanks for this - was thinking about doing something similar myself.

 

I thought it might be nice for a script to look at the parallax used on the map, then look for another file of the same name, with a prefix or suffix, and just automatically use it if it exists - would save designer having to change the script to specify the second layer name. Would be a drawback though if you had 2 layers named appropriately and only wanted to use one of them for some reason.

 

And thanks for making this available for commercial projects

Hmm, that could be a neat way around it yeah, also it could seem a little more user friendly!

Also, edited with a quick bugfix.

I get an error

 

"Script 'Second Parallax Layer' line 47: NoMethodError occurred.

undefined method `bitmap' for nil:NilClass

[achille 1]

For those who recive that error message, just repleace in Spriteset_Map at line 54 :

 

def create_parallax

@parallax = Plane.new(@viewport1)

@parallax.z = -100

end++

 

With :

 

def create_parallax

@parallax = Plane.new(@viewport1)

@parallax.z = -100

@parallax2 = Plane.new(@viewport1)

@parallax2.z = 201

end

Apologies for the delay, I've been really busy with, well, everything.

I've completely re-written this to be better, and hopefully bug-free, enjoy!

 

Updated the first post with new information.
