If the hitbox is the area where a character receives damage or the area where a projectile deals damage, then the Collision Rect is the range of an event that the character cannot step into.
Usage: For example, an event with a giant monster spritesheet. If you don’t change the Collision Rect, the character will be able to walk right through it.
How to Change the Collision Rect
Add this comment to the event you want to change size.
<collisionRect: width, height, offset X, offset Y> (tile unit)
Example: <collisionRect: 1.2, 1.2, 0, 0>, <collisionRect: 5, 5, 1, 2>
From the example above, 1.2 width height = your game tile size, by default should be 48, but with addition of .2 of that tile size.
To see the visual of Collision Rect, press the button you assigned in plugin parameter which to show collision area (by default is 0). The collision area will display in green.
