The following method will search through the tile map. If a slot is filled with the value 99 that means the corresponding tile needs to be deleted.
1. Insert a method header named
ClearGemsinto thegameclass.Method ClearGems:Int()
2. Start two FOR loops, one for the rows and one for the columns.
For Local r:Int = 1 To rows For Local c:Int = 1 To columns
3. Check if the tile map contains the value
99.If tileMap[c-1][r-1] = 99 Then
4. If yes, initialize the slot.
tileMap[c-1][r-1] = -1
5. Next, perform a touch check. The current number of columns and rows has each to be multiplied by
64(the image width). The ID is set to99.layerGame.TouchCheck(c*64.0, r*64.0, 99)
I'm sure you wondering why we use a touch check. Later, in the
engineclass, we will check inside theOnObjectTouchmethod for this ID and then remove the object.6. Close the IF check, both FOR loops, and the method.
Endif Next Next Return 0 End
