Pixel positioning bug

Hi, so I've been playing around with the platformer template, I decided to try importing one of my sprites and get firing guns working following this tutorial:

youtube.com/watch

I ran into problems with the pixel positioning of my graphics, firstly the player sinks into the solid platforms for some reason as shown in the image below:

I set the origin to the base of the player as the previous graphic had:

Even when i fire projectiles it spawns in different locations when I move around, the higher up the level I go the closer to the character they spawn. (the position is not static).

Here is my event list, if that helps anyone:

Its probably quite obvious to you guys, but for the life of me I can't tell where I've gone wrong.

Thanks in advance!

Double click your object and check your Set Collision Polygon located right underneath the Set Origin and Image Points.

Your bullets are spawning on layer 0, but at least you gun is on layer "Game" - I'm guessing they aren't the same, and you have parallax values on layer 0 (background).

Thanks guys, its fixed
