Hiya there I realise this maybe already asked but its really hard to really check, I mean this is post 970 xD
I’d like to ask about implementing a few different mechanics, I’ll bullet point them and hopefully ones that have already been asked you can direct me to or whatever 
-Fog of war. Ideally I’d like it that the squares outside of a units range would be dark or non viewable?
-Doors. I’d like to better control where players can move and I think doors would so this however implementing that with unit interaction etc I imagine would be difficult?
-Camera blocking. I’d like to limit where the camera can move so that players cannot move the camera off the map however when I tried doing this, I cannot stop the camera from moving away from the grid.
-Wizards or custom units. I realise that you’ve done a video on both importing your own units and destructible pawns, this is great as it is one of the mechanics that a unit I plan to bring into my game. however I would also like them to have the ability to heal or defend other units, is this a possibility? or will it be very difficult to implement?
-Objectives. I would like to make objectives in levels so the win conditions are not simply kill all the enemy. For example steal/loot/pick up this thing, save/capture/help this unit, kill this particular unit. how could I do this?
-One team progressing through levels. So the idea of my current game is that I am going to be doing a campaign of a series of levels that the player has to take their team through. Meaning that players will have to choose their team at the start of the campaign or perhaps at the beginning of certain levels eg choose how many melee, ranged and wizard units you want in your team. This also means that teams have to progress through the levels so the game has to bring them from level 1 to level 2 which I am not sure how to do.
Thanks in advance! I realise this is a lot to ask so I apologise about that and completely understand it may take a while or not be possible to do everything, but these are things I’d like to do and if its possible that would be great =D
