Re: Floor Perspective

[Sergey Mukhin]

you should use a few SurfaceLayer's on background, ImmediateLayer for character rendering.

to move over a background change (x,y) coordinates and use layer.setOrigin(x, y); method to change SurfaceLayer position.

Also you should think about background repeating so draw 4 backgrounds and to switch between it use a % operator (modulus)

layer.setOrigin(x % (layer.width()/2), y % (layer.height()/2));

The problem is that the background isn't "repeatable" because it is a pretty complex image (and for other reasons as well), so I actually need some kind of function that allows me to stretch the image and give it a sense of perspective.

I found a perspective filter on this page http://www.jhlabs.com/ip/filters/index.html (source code here: http://www.jhlabs.com/ip/filters/Filters.zip) but I have no idea on how to implement it on PlayN...

check ShaderTest from here:

https://github.com/threerings/playn/blob/master/tests/core/src/main/java/playn/tests/core/ShaderTest.java

it has some kind of image perspective you need.
