cocos2d iphone - Box2D and sonic-like physics for platformer -


I am working on a platform for the iPhone which is using Box2D and cocos2D.

I am trying to find a way to create a behavior similar to my controlled character, as is found in Sonic Hedgehog Games, but want to keep using Box 2D Physics Library because I Conducting projectiles and some level objects according to realistic physics is some situations related to controlled conditions (Jump, Barringling in objects D).

The main issues that I am running are characterized on the earth, from when contacting the ground by going to convex curves and maintaining emotion, unless there is no significant distance from it. Is performed. When I want to react only to the character on the left and right commands on the ground, but if there is a slight decrease, my shape is the habit of leaving the ground, as the reaction time is delayed for a while unless we reinstall it. Apparently there is no separation, but it is enough to change the situation on the ground or not, besides the character "throat" does not grow the way I would curves.

When I have tried to raise an additional downward force on the ground, but it does not work quickly for large curves, and big forces interfere with the character's regular movement to be effective. Any thoughts on these issues?

In my experience, you need to feel like a true console, unreal physics, especially the player for.

I believe that in Box 2D you can use impulses to hack the movement system, while reaching for the detection of confrontation is still reaching. It was either, or is making a non-moving object to your character, and I am making a movement, I forgot that it seemed to work for me; It has been a few months; I believe that something In cases where I have done anything to fix the bugs (slopes) to fix anything to the vectors on the Y axis.

If your movement is working properly for the general case, then you can create an agitation when there is a special case in connection with the land with the curve, where you take the physics in your hand , And just hang out in the real world to find collision.

To use one more option, most items use "fake" physics, and only to detect collision, or box2d for "realistic" objects.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....

wpf - Custom Message Box Advice -

Well, I'm using a custom window box that comes with some custom control boxes that accompany the text The producers who are displayed are called. I have a defined event, which has been subscribed through the original class, it gets burnt when clicking on the button. However, I can not see how to use it effectively, I would like to return one yes, whether yes or not, but obviously my code will continue to execute, so this Below is some example code to clarify the problem that the method has subscibed by clicking on the button. Message box window Public partial class custom message box: window {public representative message messagebox object sender, event events e); Public event messagebox handler messagebox document; Public Customs Box () {Initial group (); } Public Customsbox (String Message) {InitializeComponent (); This.txtdescription.Text = Message; } Public Customsbox (String Message, String Title, String First BTNtext) {Initialization (); This.lbltitle.Content =...
