just to be more specific, if trying to use two layers, one with the image
unmodified and another with "empty" cells
- as Daniel said, the Scene would be composed as
scene
scrolling manager
Scrollable layer (z=0)
Sprite with the image (*)
Scrollable layer (z=1)
hexmap filled with "empty cells"
- "empty cells" *must*
+ have a tile to change colors (else no action or exception)
+ the tile *image* should be a solid color (if you choose white
then you can use multiple highlight colors, transparent will not work or
will produce unexpected results because color and opacity multiplies the
pixel values)
+ the tile image needs to have a specific relation between width,
height and hexagon side; for testing purposes use a copy of the tile in the
cocos example, painting it to solid white in a graphic editor
+ transparency in any (highlighted \ non-highlighted) state should
be low to allow view the image behind
+ each state has it own (color, opacity) values; opacity==0 is
acceptable for one of the states
- this implementation will look as is they were tinted haze between the
image and the eye, with possibly one state having no haze (opacity=0). It
may or may not work visually for the effect you wanted to achieve,
(*) if your texture is smaller than the max size allowed for the hardware:
for modern hardware 4K x 4K, older 2K x 2K or 1K x 1K. If image bigger,
then you can partition into a rectangular tileset and show as a rect map
