Shapes

From this menu you can select from Gamemaker's built-in particle shapes.

Sprites

In case shapes aren't enough, GPV allows you to import .png files and use them as sprites.

How to create a sprite

1 - Click on the "Create sprite" button at the bottom of the left menu
2 - Select a .png file from your computer
3 - Set up all of the sprite's informations, these cannot be changed later.

The sprite is now done, you can select it from the sprites list. Sprites are compressed and saved into the .GPV file itself so you won't have to worry about the original .png file, but they can take a lot of memory.

Note: when asked about how many frames the sprite should have, GPV will divide the image into the frames.
