wow! thank you very very much. it's so simple and already fun to play with

the next thing i will try to implement is some kind of imaginary line that crosses the screen. only when all polygons of the castle lie below this line, the castle can be considered as "destroyed". any ideas how i can implement this?

Hi,

Right now I am working on a simple game with physic objects. It's goal is to destroy a building with some kind of projectile (e.g. cannonball + catapult). Here is a first screenshot to visualize my ideas...

The building on the right side, as well as the cannonball on the left are made up of objects with physical behavior. So far so good. Now my problem: I want to integrate a Drag&Drop control for the catapult. The player should have the possibility to drag the left part of the catapult down and then let go in the right moment. The further he drags it down, the more impulse is given to the cannonball. Is this kind of control possible in Construct? And how?
