I looking for a script for ray-collision in coffee (like the ray-collision in XPresso).
Anyone have an idea to do that?

I'd use an existing algorithm as there is no ray-collision in COFFEE (there is a GeRayCollider in the C++ SDK).
The best approach is first by decreasing bounding-box elimination (objectgroup-objectgroup, object-object, polygon-polygon) and then two-way ray-triangle intersect tests. This usually involves taking rays off of the one object from either random surface points (random point in triangle algorithm) or vertices and triangle centroids (or both).

Thank you for your answer. I solved my problem and use the normal ray-collision with coffee-nodes.
