Greetings !

I have a game where the player should collect the alphabet coins in its correct order.

map is really big , this is just 1/16 part of it.

Coins you can see are being spawn using Random.Range with min/max X and Y … all this works fine until coin is on CircleCollider (like on letter “C” on the left) where car can't get on to … this means that game is automatically over and player loses because of the thing I have not yet developed.

The first idea for the solution is to put exceptions for each object for coins not to appear on that place … those are trees , buildings , etc … Buildings on my map are over 100 , trees about 100. I don't think that exception is a good idea. Yes I need an idea more here/today and not the code (but I would appreciate if you give me the idea for a code).

How I can spawn my coins that way so they won't be on some objects (I may tag them and then use).

Please assist ?

and thank you in advance

You could approach this in a TDD-like manner. You have your procedure which for each random point places a coin.

You could invent a function for it - a test step - that must return true, or it would have to try another point to place that coin at.

Let's call the map's new function isItOkToPutACoinHere(x, y)

Invoke it from a test, using a known map, and you should then expect it to return false on the tree, and true on the lawn.

Next, you implement that function; for all objects, check, or from a point in a precomputed/maintained map, check.

Solved ! Thanks to everyone
