The tilegrid plugin is an object that works as a unique-object grid, with several properties/conditions/events that may be useful.
You can assing to each cell a unique value.
Properties :
Number of cells (X,Y) = 1,1
Items... (Here you can choose the values)
Conditions :
Compare at (X,Y)
Compare number of cells (X,Y)
For every cell of X type
Pick one of them
Events :
Create object at cell (X,Y)
Create object at picked cell
Assing value at cell (X,Y)
Why should it be useful? For example you have 3 types of crates : 1, 2 and 3. They're sprites. If you are going to make a puzzle game, you can easily position these sprites in a grid graphically, and manage all the puzzle events by grid cells. Example :
->For every cell of 1 type
+ Pick one of them
= Create object at picked cell
