You can..

Right click on a polygon point and choose add..

Without your capx it will be nearly impossible to see what is wrong..

Shakes animation is not a very clear description, I must say..

Have you checked the origins an collission-polygons of your animationframes?

When you open up c2 and choose new project there's an example of autorunner..

If instead of is overlapping you use is overlapping at offset x=0, y=1 it will work..

Inside the image editor bottom shape on the left is the collision polygon tool..

You are going to need multiple shapes (not 60), because a collision polygon only has an outside, so you can't have an open space in the middle..

You can call javascript functions through the browser object..

Wacom Intuos FTW..

Add Krita for painting/drawing and you'll never need paper again..

you can add a tag to a sound..

if you set that tag to the enemy.uid

you can stop the specific sound that that enemy is producing..

looking at the debugger currentstamina goes directly to 0 when moving..

Also I can see you are setting the width of the staminabar in th stamina-consumption eventsheet and in the hud event sheet..

it makes it very unclear for me to get an overview of what the actions should be..

should be something relatively easy as:

when player is on conveyerbelt - player set x: player.x+1

Could you eleborate?

what does mouse sensitivity mean?

Instead of using

replace:

touch is touching thumbstickstick and touch is touching thumbstickstick2

in the last events to:

thumbstickstick is selected and thumbstickstick2 is selected

that should take care of the drifting away..
