I'm making a game for a school project, and I chose PvZ. It is going well, but I need help with 2 things.

1: How do I make something dragable only once?
2: I have made it so that when a seed packet is click, a clone of the packet's plant is made, but whenever I drag (example) a sunflower, the sun appears by the main one. How can I fix it?

Thank you for helping!
Or don't…

1. Use a variable. Assuming you're using clones

2 you need to share the project to work that out

For the draggable only once, make it so that the clones stamp themselves then delete the clones, and to make the plants functional make an invisible-costumed sprite that goes to the stamps to make them function. As for the sun appearing by the packet, I would suggest putting the generate sun script under when I start as a clone but it's a little harder to identify the problem since we can't see the project. Please share it and give a link.

Can I have a simple explanation. I am using GIFs and clones. Does that help?

I would go the route @drmcw said unless it doesn't need to run code.

I'm trying that script word for word but it's not working.
And thanks for the quick reply.

It probably just needs to some tweaking to fit your game. If you share the project and give us the link we can work it out quickly.

At the start of the discussion I said how this was for a school project. The teacher said the getting stuff off Scratch is fine, getting helped is fine, but getting someone to do it for you, or copying someones work is a step too far. It's ok if you can't help.

Hmm… Maybe I can walk you through some possible bugs. You are creating clones right? You probably want something like this for the ‘spawner’

This would just get a clone ready to be drug.

Also, check to make sure its a ‘local’ (this sprite only must be checked) variable.

Literally just fixed problem 2 as I got your mail. I had on!
Thanks any way though.

Still need help with how to, for example, sun to a cloned sunflower.

And rounding aswell, so that I can plant them on the squares

I assume you mean having a flower make a sun. Try something like:

Thank you alot!
And sorry for my typo.

What about a projectile?

You can take their x and y position, divide it by the number of rows/columns, round that number, multiply it by the number you divided, and adjust for where the columns are. So, for a 4x4 grid starting at 10,10 it would look like:

For pea shooters, have them make a clone. To keep track of what type, have them do this:

How do I decide what MY 10 x 10 would be?
And I've done all the rounding and all that, but when a sunflower clones is placed down, I end up dragging multiple clones. Why?

Multiple clones must have been created. Scratch updates 30 times per second so user inputs can be activated several times in the code with one push of a button or click. Also, I think my code might have been off, give me a sec to find a better one.

My bad. It's not row by column, its the actual size of the rows and columns. So if it were 4 pixels wide by 4 pixels tall. Your probably have like 20x20 or 30x30 pixel cells.
