Platform Movement Object - cannot detect 2 objects

[pinacoladaxb]

I noticed that when using the Platform Movement Object extension, the player cannot stand on one active object while it is overlapping another active object. If you don't know what I'm talking about, go to the example file for this extension. Then, click on the "Branch" and drag it over to just above the "Moving Platform." Notice that when you are on the platform and collide with the branch, you fall through the platform. Is there any way to fix this?

EDIT: To find the example file quickly, click Start>>Run and type
C:\Program Files\Multimedia Fusion Developer 2\Examples\Platform Movement\PlatformMovement.mfa
If that doesn't work, you either don't have it installed or it is installed in a different directory.

I can't replicate this glitch, might because im doing something a bit differently than you.

Could you set it up exactly as you have it, and post the example so I can test it out?

Edit: Woooo, another person from Pennsylvania!

OK. Here's the example with the changes:

Yes it is problematic. I use PMO for a long time but never found myself in this particular case. The problem is that PMO won't work well if the player overlaps more that one jump-through platform at a time. You can also test this if you pile up branches.
The problem isn't really solved by changing the jump through platform collisions setting in the object setup panel. You'll be able to stand on each platform, but sometimes you'll float some pixels above the platform.

The solution is to arrange your plaforms so that the vertical space between them is always equal or greater than the height of your player detector. Hint: Your could reduce the height of your player detector and/or raise his jump strenght.

Thanks. I'll keep that in mind. I have one more question. How do you make it so that your player stops when it is standing on the bottom of the screen? I tried
•Detector>>leaves the play area on the bottom
•Platform Movement Object>>Test for obstacle overlap
------Platform Movement Object>>Selected object overlaps an obstacle

Why didn't that make the player stop? Instead, the player stopped after it had completely left the screen.

From the PMO help file you have to test for "Detector is not in play area" (negated event). But that doesn't seem to work anymore. Maybe something has changed since the initial release of this extension.
The workaround is to create obstacles that surround the frame.

Most likely not. The 'outside frame area' check is an MMF2 thing, and not directly related to the platform movement object.

One working solution is to use

Y position of Detector > Y Bottom Frame

...instead of...

Detector leaves the play area on the bottom

...as you can add an offset to my solution.

Thanks, Nifflas and OlivePearl!

I have one last bug, but I'll fix it myself: only on level 5, the player hovers above the ground. He sort of moved up and down, too. It's weird. If you have any immediate suggestions, they would be greatly helpful. If not, then forget about it.
