Asset that can be used to implement curtain-like effects. It is basically a colored surface that can be displayed above other assets to temporarily hide unwanted effects like switching from one background image to another. In that sense, it acts just like a real curtain would in a theater.
Note: You can make the curtain transparent by using RGBA colors. The last part of an RGBA color is the ALPHA channel, that is, the transparency level, where 0 is invisible and 1 is fully visible.
Defining the curtain in the assets section:
. curtain ~my_curtain, color white
Using the curtain in a scene:
. show @my_curtain
. wait
. set @my_image, image image_name
. wait
. hide @my_curtain
