Best Way for Platform Enemy AI?

[Blue66]

Hi there!

I have looked up a few tutorials about how to make platform enemies with basic AI using detectors for sides and bottom, there are a few about the bouncing ball movement and some talk about making the enemy a platform movement object of second player and disabling the controls for that etc.

I've tried a few out, but there always seem some problems with each method I try. I'm sure there are some of you guys here that can help me find the best method for this. What is your method to make platform enemies that can detect the levels and jump around or whatever?

My main problems so far:

When I use detectors/platform objects for enemies, I can't get them to communicate with eachother properly, even with spread values. For example the health of the enemy is 0 or below - it should kill the enemy and the detector.

-"Health" of "Enemy" lower or equal 0
-"SpreadID" of "Enemy" equals "SpreadID" of "Detector"
--destroy "Enemy"
--destroy "Detector"

But it doesn't work

My question is, how can I get enemies to communicate with the detectors properly. Or even better - is there a solution where I don't need detectors? Like make enemy AI using Platform Movement object or something?

Thanks a lot guys and have a great day!

"SpreadID" of "Enemy" equals "SpreadID" of "Detector"

Note that expressions do not and can not select objects, so of course your detectors are not being narrowed down to the matching one. Also, your event will not work in the case that more than on enemy needs to be destroyed (ie some explosion kills them all). But for now, I think it can be fixed if you do it more like this:
Health of Enemy is lower or equal to 0: Set Global Value A to SpreadID of Enemy, Destroy Enemy
SpreadID of Detector equals Global Value A: destroy Detector, set Global Value A to -1

Just make sure Global Value A starts at -1 or it will destroy the first detector with spread value 0.
