Hi. So after some tweaking/experimenting here and there, I've figured out how to add some pretty cool stuff to this engine I've been making.

Current features include

• One script handles everything
  
  • only 3 arguments, move right/left, and jump
• Pixel perfect collisions (Even for ridiculous speeds)
• Jump-through objects
  
  • Slopes (height can be defined)
• Non-Passable objects
  
  • Slopes (height can be defined)
• Gravity direction (No, not just right/up/left/down. Any 360 degree angle)
• Bugless (?)
• Works in GM Lite & Pro

So, this has the bare minimum of features, and I don't plan on adding anything else. I also neglected to comment the code, so I suggest you be skilled at GML before trying to edit anything found in the script, unless you want some bugs. Credit IS required.

Check out my Platform Slope Tutorial featured in the Tutorials and Examples forum for a better understanding on how and why this engine works.

Enjoy.

Sorry I can't resist;
"Basic Advanced Platform Engine"

On a side note it sounds pretty good. I'm going to download later when I get home and give it a shot.

Works great, even at higher speeds like you said.

Not much else to say, awesome work.

[fredcobain]

Really perfect! Congratulations.


The code is difficult to understand, but the behavior is perfect.

[brod]

Glad you all like it.

[Drandula]

Really good work At first sight I didn't fully understood your script ^^"
But it works perfectly and thanks you remembered adding easy changeable
values. This is great example for my little brother. (I'll show it right after I get from hospital)

Cool! Good for newbies

[holystorm]

Can't download, page not found.

[brod]

Sorry about that. Fixed.

Woahh! After testing this and other examples (found on your page), I was shocked, how good they are! Small file size, really good scripts; only one word to say: brilliant!


Edit: Can you spend a little bit time to expnad your example? Such as a small moving Platform?
Would be really nice!

Nice one! I've looked everywhere for this kind of thing!

There is one issue though.

When only partially jumping through a slope (made of multiple slope objects) the higher part of the total slope (another object) is ignored and my character does this:



He basically stands 'between' the slopes, which is rarely a desired behavior. You wouldn't want your character to walk through the 'floor' would you? I think it could be fixed easily, but I wouldn't know how to edit your code to do it.

Also, I know it's asking a bit much, but does this happen to support basic moving platforms? Either way, it's still awesome as is. I'll definitely add your name to the credits of my game when I release it! Thanks a ton dude! I honestly do appreciate your hard work!

I have updated this platform engine to fix the slope problem I encountered as well as added dropping down from above jumpthrough platforms. I also added moving platforms as well as solid moving platforms. Moving jumpthrough slopes are a bit messy and I doubt I can fix them without understanding Brod's code better, but so far, my edit is pretty good! I've actually got a better version than this with much more advanced and customizable jumping (including variable double, triple, etc jumps). Just let me know if anyone wants me to upload it. For now, here's the older edit of Brod's engine with lots of commented code:



If anyone edits it and updates it, please post in my Zero Engine example thread.

I know my moving platforms aren't perfect (mostly the solid ones), but if anyone can mesh my code with Brod's slope code a bit better, it'd rock if you'd share. I've pretty much commented everything I've done, but Brod's slope code is still some kind of voodoo to me and I've put a week straight into coding the basic moving platforms so you'll have to fix them yourself if they don't work the way you might want them to. I only needed the moving jumpthrough platforms to work. Even so, it shouldn't be too too hard to fix the moving solid ones. I just got tired of messing with them.

[Billyro]

this is a really great engine!
I could easily modify it too.

(FINALLY! An engine with jumpthrough slopes!!!)

I'll give you credit for it's use.

This is a great engine!!! Good work!
I set the max speed to 80, acceleration to 8, and room speed to 100 and it STILL had perfect collisions(although it lagged a bit:lol:)
It's a shame I refuse to use any engines but my own

Ace has a nice edit going, be sure to check it out.

[True Valhalla]

Very nice engine.

A great addition would be movement syncing based on FPS.

Here is my platform engine (nowhere near as good as brods!) but it does contain functional platforms in any direction at any speed, which you can jump off (and if you jump off moving fast upwards you take on the platform speed too).

Problem is I can't understand Brod's code. Mine is a lot simpler (but less efficient) and it has explanations all the way through.

Here's a link to the source:

http://host-a.net/ma....html/ninja.gmk *EDIT* Updated file to include more platforms

If someone clever out there can reconcile the two it would be greatly appreciated, I really want to use Brod's engine from now on, it's awesome.

Btw, I've decided to take up some edits on this engine.

http://gmc.yoyogames...howtopic=454506

Read over my previous post here and check my new topic for my new edit that includes moving platforms and lots of commented code. If anyone wants it, I'll update the download link to include more advanced variable jumping, bugfree of course, that also includes double, triple, etc. jumping built in.

[brod]

New cool thing I realized, this works with Lite as well as Pro.
