How to import custom textures and custom sprites

I thought I'd just make a quick tutorial on how to do these things since I struggled a tiny bit

(also, please note, I am not an expert so take what I say with a grain of salt)

Setup:

First of all you'll need to download SLADE and your editor of choice (however this tutorial will just be assuming you're using Ultimate Doom Builder)

• Make the .wad file you want to add custom content to and save
• Open the .wad in Slade

Textures:

• Make/download the texture you want to add
• On the top left of the screen with the options, go to archive > import files

• Import your texture of choice
• Inside of Slade, right click the image file and hover over graphic
• Select add to patch table (If it asks you for a texture definition, select "Yes" and then in the new menu click "OK")
• Go back to graphic and click "Add to TEXTUREx"

• Save the file (You can save the file at any point)

Now you've got your custom texture!

Sprites

Because this is the mistake I made, I'm going to start this off by saying do not put your sprite file location in between P_START and P_End

• Select the green paper to make a new entry. 

• Create two entries, the first one called "S_START" and "S_END"

• Add your sprite image
• If the file isn't inbetween the S_START and S_END entries, select the image and use the blue arrows to move it between the two entries

• Save your file (You can save your file at any point
