What do you mean? If you want to customize your character, you could try this:
Create a new layout to locate the editor, and set up the editor. You can create a new sprite for every single customizable "item", for example, a sprite for the sword, a sprite for the clothes, etc... Every sprite has many different frames, every frame is a different sword/clothes/etc and in the editor, the player can choose the frame he likes the most (choose which sword/clothes/etc he likes the most). Create a variable to save the value of the frame the player has chosen and then, in the game, the sprites that compose the character have to set the frame of the variable.
