How do I detect specific tile collision (Events) - SOLVED

Hi guys,

I want to detect collision / overlapping in "Spike" tile, I dont want to use 2 tilemaps 'cause I need to create a Mario Maker clone, save tilemap, open tilemap.

If I create an invisible sprite for each spike tile, I'm afraid to affect the performance, it's a mobile game, and at end of each level, the next level start immediately.

This is my actual code:

----> DOWNLOAD CAPX <----

(Player behavior: drag & drop)

Works fine on left and right collision only.

Some ideas?

EDIT:

Sorry, I solved it, I had inverted the X and Y coordinates. If someone has the same problem:

----> THIS CAPX WORKS FINE<----
