First, you need to install the main mod. If you don't have this mod, you can't use the player model.

You need at least one image

Then create a folder inside the addons folder
Then create materials / 2dplayers directory
Then create a folder with any name, the name of this folder will become the name of the player model
(_) Will be automatically converted to spaces

Then create a default folder

Now you need to add a image
Like the
The name of the image is preferably a number, if you want the player model to have animation effects
You can add many images to make animation effects
Then open game, you will find that the player model has been added to the game

Used so all image can be found here[github.com]

You will soon find that you cannot see your weapon model, this is because the weapon model is hidden, but you can make 2d weapon models

First you need to know the world model of the weapon, for example, the world model of crowbar is (models/weapons/w_crowbar.mdl)

Now that you know the path of the model, go to ((mod name)/materials/2dplayers/(player model name)/)
Then create the models.weapons.w_crowbar folder
Then you need a picture of a crowbar
Then you need to copy the images, for example, there are 13 player model pictures, then I need to copy 12 images
Like the
The images are automatically combined together, so only the image of the weapon is needed
Then in to game, you also can use command (qtg_2dply_reload) to reload 2d player model
Then switch to crowbar weapon and you will see the effect

If some weapons do not have any models, such as fists weapon, you can directly use the weapon name to create a folder
You can also make images of jumping and death

You can customize against the template
