Feature Request help to create 3 match unity2d

I'm making a 2D match 3 game.
Help please, I need to make a field in the form of a pyramid and an hourglass, but I don’t know how, I can’t delete or hide the balls

I am attaching a link to the project, I hope for your help

You need a way to author that shape, eg, some way to put data into your program that is used to decide where and what to spawn.

There's a million different ways ranging from hand-typing all the coordinates one cell at a time, or making a function that generates positions as you like, up to making a complete interactive game editor.

If you want a simple example of using a texture to spawn stuff, I have such an example in my MakeGeo project.

Look for the

Bitmap2Grid

scene and associated code.

MakeGeo is presently hosted at these locations:

I am assuming your game is in 2D perspective.
For a pyramid I guess you can use a simple 2D for loop to spawn your gems in a triangular shape

An hour glass is also just two triangles mirrored.

For any other complex shapes you can try the hand typing coordinates method or the other methods mentioned by @Kurt-Dekker
