Altered Melee

[Mochi King]

So, what I wanna know is the trigger for choosing things. I'm wanna make an altered melee map that let's you choose between the stuffs (like which race you wanna play as), and I also wanna know how to change the workers and the town hall n stuff.

This can be done using a dialog.

and I also wanna know how to change the workers and the town hall n stuff.

Daffa and polardude shared their respective methods here and here. You can use them as references.
