Weird problem with MMF2

[Alpha]

Hi guys,
I have a big problem and I don't understand how is it possible to happen!

I'm trying to code the AI for the enemies of my game and I noticed this problem.

writing the following code...
+ Collision between Player and Enemy
+ Enemy ID = 1
= Then sub 1 to Player's HP

isnt' the same thing as writing the following?
+ Enemy ID = 1
+ Collision between Player and Enemy
= Then sub 1 to Player's HP

I mean... I always tought tha switching the condition's order does not change a thing. Am I wrong?
Because in the first example, nothing happens... while with the second example the PLayer's HP are correctly decreased.

So what could be the problem? Maybe a bug?
Somebody did experienced the same problem?

Thank you in advance!

I do know that MMF2 is sometimes picky about the order of events.

Alpha, i THINK that if the condition in red is first, then when it happens, it wont have time to see if the Enemy ID = 1, so nothing happens

"Collision between Player and Enemy" is colored in RED and has to be in front of all the other events or it will NOT work.

"Collision between Player and Enemy" is colored in RED and has to be in front of all the other events or it will NOT work.

I think this is opposite in his code that works?

Red events are triggered, they do not use an equation to return true or false (unlike "Compare global value" etc.)... if they're red at the top, leave them there. You can't combine multiple trigger conditions.

First of all, thank you guys for all the answers.

I knew that collision conditions should be put on the top, but this time it only works if I don't put it on the top.
I don't understand why.

I mean... even if it was the other way around, putting it on the top would only run the game smoother, but it won't change completely the result of the code line.

What I don't understand is why if I switch the conditions order I don't get the same result from my code line.
The order of actions is important but the order of conditions is not as much important.

Am I wrong?
Could it be a bug?

It could be something you are trying to do in your app/game. Maybe upload an .mfa we could look at to determine the problem?

MMF goes through the conditions from the top down selecting objects to act on as it goes, so the order of conditions in an event can make a difference in certain cases. It's a bit difficult to describe the nuances of all of the conditions, though, and your example at the top definitely seems to go against what I would have thought would work at first glance.
