Changing size

I am planning to have a large boss for my game, and I need to know if it is possible to change the size of an object in order to do so. So can I?

There’s a size behavior under properties. 100% is normal sprite size and anything else will make the object grow or shrink. You can also mess with X and Y separately so it can be taller or longer…

Here’s an example using X & Y;

If you want more pixels or just a bigger object for more colors and look, then open the sprite editor. Click the blue icon on the bottom right corner of the tools. 2 sliders should appear on the bottom of the screen and you can increase the sprite by 32 pixels (1 block) tall and/or wide.
