Platform game movement questions

[Endymian]

I am having a lot of trouble figuring out how to make some of the add-on movement controllers to work. I guess I'm still learning here, but primarily what I am trying to do here is limit the player's ability to change their direction in the air mid-jump. Does anyone know of an adequate solution for this?

I am also trying to set up an event where the platform character can only kill an enemy object when jumping onto it from the top and while holding a particular button. Does anyone know of a way to do this?

Thank you very much

For the second question. create a small flat bar (Active object) and put it on top of the characters head. Go to the event editor and do:
>Always
- Set possition of flat bar (on top of the enemy)

and

>Start of frame
- Create flat bar (On top of the enemy's head)

now to kill:

>Player collsion with small flat bar
+(Insert new Condition)Upon pressing "A BUTTON"
- Destroy enemy

Do it like this, but exactly the other way around. Set the small flat bar to the feet of the player, and also important don't do "Upon pressing" but "Repeat while holding".

+ Small flat bar is overlapping enemy
+ Repeat while holding "A BUTTON"
> Destroy enemy

Else you get association problems, and all enemies die if you touch one. And concerning the button, nothing will happen because the player collision was already an immediate condition and so is "Upon pressing key". You don't want that

Concerning the movement controllers..
What exactly do you have set up here?
If it is a custom movement, you want some sort of horizontal speed that increases from holding left / right, while the player touches the floor (acceleration) and decreases from touching the floor while NOT holding left or right.
If you restrict it to touching the floor, the player can't change direction in the air.

Which custom movement extension do you recommend to best pull this off? Thanks!

Weeeell, personally I wouldn't use a custom movement extension at all. But you might use the help of some extra objects - e.g. the advanced direction calculator (or advanced math object, if you want to vitalize it).
The advanced platform object can definitely save some time, of course at the expense of control. But if you don't know yet what you're doing, that might be welcome

Hmmm, I appreciate the input but I still don't know if I quite understand.

I know that this project won't need to be vitalized, so the advanced math object is ruled out.

Do you think the advanced platform object is the way to go then, or can I get away with it using the built-in platform controller with the assistance of the "Advanced Direction Calculator" you mentioned? Either way I am going to need to do intense help-file reading and self-teaching in order to understand the extension. A lot of this add-on business is very new to me. Are there any example files that might help me to understand it better?

thank you again

The built-in platform movement pretty much can't be helped. So if you don't like it's problems, there's not much of a chance of fixing them.
The solution is the advanced platform object or a roll-your-own custom movement.

Usually every extension comes with examples and a manual that are located somewhere in your MMF directory. If you use the extension updater, those will -not- be there (complaints to the guy who made that thing :P).
