Trigger actions and/or effects

Hello,  Probably really simple but I have no idea, please help. Is there a way to programme a specific square/hex on a map so that when a character token lands on it, a special fx auto triggers/happens. I just want an effect, not bothered about triggering saving throws or rolling damage or anything.  I was playing about with the teleport API recently and thought that if you can programme a token on the GM lair to teleport a character token on the token lair then maybe there is a way of a token triggering a special effect like "Nova-Blood" for example?  Is it as simple as a macro or is there an API I need to install? If API I can move this to that discussion group.  "Keep the blood off the streets" :-) 

You could do that with it's a trap.

Yeah thank you, I have been watching the YouTube video regarding this and it seems a lot of faff for what I am looking for, I may give it a spin to see if it will work for what I want.  I am not looking for saving throws and damage and passive perception checks......just a triggered effect when a token stands in a certain place on the map. Automatically. 

You don't need all of those for its a trap.

I put one trap which is a magic burst of fire three squares away from a bear trap, set them up completely separate from each other, yet when someone stands on the fire trap the bear trap goes off too.
