   I am having so much trouble with this!!! :@ I've posted the same thing on so many sites without getting any good help!!! So plz help me if you come across this!!!!

   I've made it so my character can walk along slopes but he dosn't really stick to the ground and it's really choppy not to mention he cant walk up slopes that are too steep!!

   I don't know Actionscript so I can't help you in your ordeal, maybe some of the other members can. But you can't put stuff like that in your tags.

   Right, but due to that recent update you can't remove your own tags anymore.
   Have you mailed/pm'd Brad about this yet?

   About that code: It's huge, and works pretty decent already. It will take a lot of time to find a way to fix it... Though if you search (bottom of the main page) around for topics about slope detection, you may get a working code. I think Steve posted one.

   Looks pretty good to me.

   The only problems I see at all are:

   1) the character "jiggles" when you're not moving
   2) cant run up steep slopes

   for 1), your problem here is that after your character is done moving you're still finding the proper rotation. wrap the finding rotation code in a if statement like this:
   if(character is not moving)
   {
   rotation finding code;
   }

   for 2), because of the way you're finding the rotation of the ground, you cant have slopes past 90 degrees. There is not a way to calculate the rotation past 90 degrees with atan2.

   Besides that looks pretty smooth. keep it up

   The game is looking nice. But you're a stupid troll. Just spamming the tags cause you want attention, makes you a troll.

   So please try to do something called ¨research¨ before posting on all the forums you can.

   This is a signature!

   oh I didn't see those tags...
   please try to keep it G man, and use tags that are relevant to you topic. failing to do so doesn't make people want to help you.

   Sorry for the tags then, I'm just really fustrated with this. I don't think the tags should be any excuse not to help me though. Anyway thanks for the reply's sadly they havn't really helped.

   well what are the problems then? I'm not seeing any besides the two I listed

   1) the character "jiggles" when you're not moving
   2) cant run up steep slopes

   are these the problems you're talking about??

   yes, and it he dosn't seem to stick to the slopes too well.

    ok, well here's the reason why he's not sticking perfectly.

    First, here's a quick explanation of what Math.atan2 is. atan2 finds the angle between 2 points and requires 2 numbers in order to work: 1) the difference of the points x positions and 2) the difference of the points y positions. With these two differences it's able to calculate the angle like so: Picture explaining how

    See how the difference between the points the KEY thing in finding the rotation? If i change the X the angle changes dramatically, same goes for Y. Basically what I'm saying is the closer your two reference points are the better. Picture Again!
    See the 3 blue ref points? the farther away they are the farther off from the real rotation they are.
    The green point is what the 1st reference point should be, and the red one should be the 2nd reference point should be.

    A bit of an over explanation but hey, I felt like talking math and drawing ;P

    i dont have any points it's just my character?

    To do slope detection you will need to points aligned to the ground. PLEASE READ THE OLD SLOPE DETECTION TOPICS. THEY ARE VERY HELPFUL.

    Another thing, and this is just general advice: When posting your code on forums, don't just post a huge blob of code and ask what the problem is. Either take out stuff that isn't relevant to your problem or at least comment what you have so we can figure out what does what. I've been dealing with my own 1000+ line piece of code lately, and I can't just instantly look at someone else's and figure out what does what, not to mention what the problems are.

    You have something very close to a workable engine, but some of this stuff you have to just figure out on your own. I don't really have much experience in slope detection, so I'm sorry I can't help. But the jiggling may be caused by the way you add gravity to your game.
