Platform Problems

[Goldenrod111]

I have a character who I want to move on some platforms. I followed the instructions for preparing it for platform movement (hotspot in the middle of the bottom row, at least one frame in each animation, and mostly-similar sized frames). If I make a backdrop under my character have the "Ladder" obstacle type, then he drops onto it, sinks slightly, and stops. In other words, it works perfectly. However, if I have the backdrop be of the "Platform" obstacle type, the player just falls through, as if the obstacle type was set to "None". Am I missing some "coding", or is there a bug in my version (Multimedia Fusion 2, not Developer, V. 2.0, Build R248)? If anyone can help me with this, thanks!

In the event editor, do you have the event "[Player] collides with the background -> [Player > Movement > Stop]"? Defining background as obstacles makes sure that they will be counted as "background" by events that mention them - detecting this obstacle and making your player object react to it might be the part that you're missing.

I tried doing that, both with the test background piece being counted as an obstacle and with it being a platform, and my character still just falls through. Thanks for the suggestion anyway. I have created something like what I was aiming for by creating "platforms" out of active objects, and telling the player to stop when it collides with them, but it does strange things sometimes. I do not want the character to be able to jump through the bottom of the platforms, and the active objects to prevent that, but the player object "hangs" in midair for a second if it collides with the bottom of a platform mid-jump. Also, if it hits the side of a platform, then it cannot move in that direction again until it stops jumping. If these are fixed, then I will be able to use the active platforms, even if the character just falls through the normal platforms.

Are you sure you made your backdrops obstacles or platforms under their properties?

Runtime options - Obstacle type

[Goldenrod111]

Yes, I'm sure.

Can anyone help me with this? Please?

Perhaps upload an example into the File Archive section of this forum - it'll be easier for people to see what the problem is there.

However, to get around all the limitations of the standard platform movement, you can either use the Platform Movement Object in the first bonus pack, or use an entirely custom movement (there's a tutorial in the Tutorials link on the right).

I'm having the same problem. Oddly, dude stands on the platform just fine in 'test movement' mode but not when I run the frame...

edit: adding the event fixed the problem. Strange that I didn't have to until I ran the application though.

[Jeff]

Did you add an event to tell it to do anything?

Player collides with a backdrop - Player stop movement

Should fix it for you.

I'm having similar problems/questions on the platform front here. A few things I'd like to know how to do... (if there is a relevant tutorial please send it my way).

1) Defining quick backdrops as obstacles make my guy get stuck when he runs into them sideways in the air, or when he bumps his head. When he bumps his head he comes down after a delay but when he gets stuck on the side he's stuck for good.

The same thing happens with walls as hovering platforms, but less often.

How can I make my obstacles solid but not sticky?

2) When I make a hovering platform into a "platform" the guy walks in front of it just fine, except his walking animation freezes. He also occasionally gets caught on it like the stickiness problem, but only when in the "falling" animation.

3) How would I program the ability to drop down through a platform (think Smash brothers or Contra)?

---

It appears that the creators of the program intended for quick backdrops to do this by simple designation, but that it's not working too hot. Unless I'm missing something. Regardless, I'm sure there must be a better way.

Also, is there a way to turn an item from a quick backdrop object to an active one? I tried doing the "create active object" off of my quick backdrop, but then it returns to a single tile and no longer repeats when I resize it.
