If they are moving too fast, they go through each other.
And by too fast, I mean fast enough to pass one of the shape boundaries.

You didn't bother to offer an alternative.

I don't know the math for polygon containment and predicted paths.
Rectangles are far easier to deal with in those respects.
They are just boxes.
No angles, no diagonal distances, just algebra.

You could use both. Check outer rectangle that contains the whole polygon. Did it hit? Start checking polygon. If polygon is a miss, check inner rectangle (contained by the polygon) to check for overshoots. Still a miss? then you either hit a small corner that the polycheck missed, or you missed it completely. Not failsafe but better than just rectangles.

you had a wiki page for the math.

I improvised slightly.

That page uses matrix transformation.
I don't understand the math behind that, so I didn't even try coding it.

Point vs Segment
 Here is how mine works:

Point A and line segment L M

If A is within rectangle L M,

and Slope( A L ) ~= Slope( L M )     << Genius (but not mine)

Point A contacts segment L M at A.

Not only do you know that there is a collision, but WHERE.

OO, you CANNOT expect to program something like this without being prepared to learn some new math.

Maybe it's safer to stay in the realm of easy math?

Meow!

After retreating into the realm of rectangle constructions, I've made some awesome progress.

Using composite objects, I can make a variety of boxy creations.

Here are some screens:

Spoiler (click to show/hide)

Take note that those two tiny squares are part of the same object, and move together.

See how they can fall on either side of the pole-tree-thing and not collide with it?

The movement and jumping seem decent enough, but I need to fix a few flaws.
I'll throw out a running demo once it's more polished.

Major wonderful success.

I've got sprites working and loading, and its starting to look like a real game.
I need to code in some standard area-loading function, and slap together a demo level to climb around.
I suppose that will only take a couple hours.
I suppose you can look forward to some really basic platforming action.

I don't know how to deal with frame rate, so if anyone wants to guide me through it, or make me some sample code,
 I'd be very pleased.

Here is a screenshot:



And here is the link:
Platform Explorer Demo A

I'll upload some concept art soon.

EDIT: Beware of frame rate shenanigans.

This version has a bit more going on:

Platform Explorer Demo B

Foreground stuff and some animation.
