In my short couple years of being on scratch, I have noticed a lack for upgrade games. I first assumed they had put a ban on them, but then reconsidered. Despite Scratch having roughly 8.5 million projects, only a handful of upgrade games are decent. This article is about showing people how to make a proper upgrade game. Remember. I am not teaching you to copy me. This is merely a guideline. Switch things up a bit! See what will happen!

Step 0.

Before we start, we need to create two variables. One named “Money”. Make sure you check “For All Sprites” before creating. The second one we can call isPurchased1. For every item we will make in the upgrade shop, we will need to create another isPurchased variable. I.e. isPurchased2, isPurchased3, isPurchased4. Make sure you assign these to the proper sprite and check “For This Sprite Only”, or you will end up with some major issues later on.

Step 1.

Perfect. Now, let's say the player has collected $500. We want him to be able to buy a speed upgrade for $250. Click on the speed upgrade button / sprite and put in the following script:

This makes it so that if the player has over $249, it will take away $250 from your money. If the player has less than $250, it will tell you you don't have enough money. The play sound and say blocks are optional and are in no way required.

Step 2.

Repeat this script and paste it into all your other upgrades and change 250 to their price. Once you have finished, you will need to set the isPurchased variable to 1. To do this, add this block to your script.

Great! Now that it sets isPurchased to 1 once purchased, you will need to test for if the isPurchased variable is set to 1. This will trigger a set of commands to prevent the player from purchasing it needlessly again. To do so, add this to our set of blocks.

Again, the say block is optional. In doing this this insures that the player can't buy items he has already purchased. Without this, your player would end up buying the same upgrades time and time again.

This concludes my upgrade game tutorial. The rest is up to you. Will you make an endless platformer with upgrades? A car racing game? How will players get money? If you want, here is one homework assignment. Try making endless upgrades. Upgrades that continue to increase in price and go on forever. Finished my little assignment?

Many, if not most projects are blank or just very simple with default sprites.

Yes. That is true. Thank you for your constructive criticism!

I think that the bottom block (at the end) should be moved to the top of the script because you would otherwise get the item, spend the money, but then it would say “You already bought this item!” but you would still pay the money. Furthermore, you should use an “If/Else” block with “If not isPurchased=1, then <insert buying command>, else <insert rejection command>. You can also use nested ”If/Else" blocks to make the buying, the rejection from not enough and the rejection from already bought. Hope this helps to make it work!

I'm actually planning to make my own upgrade game

THANKS SO MUCH

Nice it worked

cool it worked

oh why did it not work!!!

It didn't work… Am i supposed to magically create a black that can have a Variable in it???!?!?!?!?!?!?!?!?!!

Its sooo frusterating i can't add a Variable to an if then block!

Wait, I got it thanks!

I made this tutorial a long time ago, so I'm pretty sure it isn't the best way of doing this. Please explain what you're having trouble with so I can help.

Xtreme_OverLord, you aren't supposed to add a variable block to an if then block, you will need to put it into an operator block that looks like this

except put one “foo” in each box and put the front of the green block next to/in the part that looks like it's dimmer and has six sides.

hope I help=<^.^>= Check out my levels as well. Heres one of them. Your text to link here…


PLZ!!!

In the future, I would avoid commenting on old threads like this, it's best to just let outdated tutorials die .
