Fog in Fortix 2

[nbelkin]

Hello!
What is the best way to create game field like Fortix 2 with tk2d?
Here is reference:

Should I use tilemap for "fog" or i can use thousand of sprites (or something else)?
Game field 90 x 50 cells, each cell 10x10 pixels?

The main problem for me to choose best way to realize this dynamic "fog"
Thx for help!

One layer of overlapping semitransparent sprites might actually do the job - you can have these in another layer in the tilemap. Rebuilding the tilemap should happen in a decent amount of time, as you won't have physics on that layer.
The only issue you'll have is the line on the edge - you could do that with the tilemap too - just have the permutations stored in the tiles, and when deleting tiles, pick the appropriate one to draw the outline.
