I'm working on a 2D game for windows phone where the player moves blocks around to bounce a laser beams.

I need to create some simple physics for moving the blocks.

For the moment I have a simple collision class, telling me if two rectangles collide. But that's not enough because when I'm moving a block the rectangle/rectangle function doesn't work.

By Doesn't work i mean,I manage the collision but I don't how to stop the block mooving while the user sliding the block.

The collision response for the block I want is if the user tries to slide it on another object, the block should slide up against the other object and not overlap.

How would I go about implementing this functionality?

My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
