Overview
This is a guide to teach you the simplest way of making a mod, by PhotoShopping it. Because why learn AngelScript?
Getting everything ready
First, you’re going to have to choose the item you have to re-skin. Usually the easiest (in my experience) is stamps but there are multiple other options.
Navigate to C:Program Files (x86)SteamsteamappscommonCasual Desktop Gametools and copy the folder of the tool you want to reskin. Paste it somewhere else and rename it to whatever you desire.
This one is pretty simple. You see that script file? The one with the .as prefix? Rename that to the name of the folder. So if your new folder name is “hbomb” rename it to… well… hbomb.as.
This is not mandatory but is definitely a good idea if you’re considering publishing your item to the workshop. Right click the recently renamed AngelScript file and click “Edit”. Now scroll all the way down and you should see this.
Edit each corresponding field with the correct information about your item (again, not mandatory (i think)). That’s it. Now onto the editing.
Photo editing
Reskinning wouldn’t reskinning without reskinning. That is, reskinning. Just edit… them?
There should be image files in your directory. Don’t rename them. Just edit them. Some tools, like the stamps and the holy hand grenade, have single images for the item and what they produce. However some (like explosions) are animations and therefore must…be animated. That goes without saying. Each frame is stored on a grid. So, open those bad boys up in whatever photo editing software of your choice, yes MS Paint included, and just change the image files.
Uploading to the workshop
Check out this guide by the dev on how to upload workshop items. If you encounter an error check for typos then have a look at the answer on this discussion I posted.
That should be it. Happy modding/re-skinning!
