This page will guide you through how to make a new Polo for your mod.
Sprunki is used as an example here.
First off, make sure you add one onto the characters list. This is to make sure it doesn't break later.
This is located in the backdrops sprite.
Go to the icons sprite and make costumes for your icon. After that, adjust this code so your icon is placed accordingly.
Duplicate a pre-existing character. This will be your base for your new Polo. Make sure to make costumes for it and stuff!
After all that, check for the character's number in the code. For example, I copied Wenda, who is the 17th character.
My new character is the 21st, so you need to change every piece of code that contains "17" to the new character ID, which in this example, would be 21.
Go to "loop controller", and scroll here. Duplicate this line of code, and place it over the last one. If done right, it should look like this.
Then, change the duplicate 19 to 20, and the next one to 21. It should look like this when done.
This is the hard part. Go into Polo 1's sprite, and you should see this big chunk of code, shown in Image 1.
Grab a "or" operator, and drag the green code in Image 1 into the first container. Then, duplicate the last container in the big container (which should be Black's sprite)...
and slap it in the second container. If done correctly, it should look like this. Repeat this for every other blank Polo.
If all is done correctly, that should be it! Your Polo will work as intended, animation, graphics and all that.
To add a new one, just repeat the process. Have fun!
