Using this template you will be able to create a new version of the game 2048 with different mechanics.
The maximum block id is 8. But when these two blocks, whose id is 8, merge together, a new block is created, whose id is 9. But its appearance does not change, since this is not provided in this example. And therefore it seems that, two visually identical blocks do not merge.
I didn't understand the second question, I'm sorry. The block is being created in the column where the touch was
Now the block on top is always created at startup, how can I make it create when clicked? The move function start_new_round does not help.
If the block is 9, then how can it be destroyed upon contact with block 8?
Why doesn't start_new_round help? This function must first be removed from the 2nd event. Then add a global variable, for example START=0. And Make the condition [On any touch start AND start=0] then [call start_new_round and set start=1]
A block with ID 9 should not be destroyed with ID 8. You just need to change the logic so that a block with ID 8 is also created from merging blocks with ID 8. Or add new blocks so that the maximum block ID is higher and the game ends on it
