Line collision in pygame

阅读更多关于 Line collision in pygame

问题 So I am currently working on a 2D platformer game and i have realized a big issue with my collision programming. You see, to find out collisions with the player I just moved the player rect around, then when colliding i pushed the player away by looking at the x and y acceleration on him. The problem is though, when using this method, the player speed can make the player skip over targets he is supposed to collide with because the rect he is supposed to collide with is too small. For example

阅读更多关于 Print text between two strings on the same line

问题 I've been searching for a ling time, and have not been able to find a working answer for my problem. I have a line from an HTML file extracted with sed '162!d' skinlist.html , which contains the text <a href="/skin/dwarf-red-beard-734/" title="Dwarf Red Beard"> . I want to extract the text Dwarf Red Beard , but that text is modular (can be changed), so I would like to extract the text between title=" and " . I cannot, for the life of me, figure out how to do this. 回答1: awk 'NR==162 {print $4}

阅读更多关于 WPF dashed line — fix dashes during resize

问题 How can I avoid line dash resize during the window resize? Consider the following image: http://leprastuff.ru/data/img/20130315/b83eea4a7a3f07ca53a0e118ddbb9230.Gif <Rectangle SnapsToDevicePixels="True" Stroke="DarkGray" StrokeDashArray="10 10" StrokeThickness="1" /> Thanks, Tony. 回答1: Set the Height of the Rectangle to something greater than one. Currently you're drawing the upper and lower border on top of each other. As the dashed stroke draws the Rectangle's border clockwise, starting at

问题 I would like to read a sequence of integer in a line with unknown bound in FORTRAN. My question is similar to the following previous post, Reading a file of lists of integers in Fortran however I want to read a sequence of unknown numbers of integer in a line and save it in separate arrays. And successive lines of integer should be saved to some other array My file looks like this 5 7 8 9 10 13 # should be stored f(1)(6) arrays 93 102 92 # c(1)(3) 105 107 110 145 147 112 # f(2)(6) 97 98 # b(1

How to plot line in matlab with theta/rho data

阅读更多关于 How to plot line in matlab with theta/rho data

问题 As title I only have the theta/rho data the line equation is x*cos(theta)+y*sin(theta)=rho how to plot line whith these data in matlab? are there any function which input are theta and rho? thanks 回答1: Just use some simple Algebra to find out how y is related to x . Take some range for x: x = -10:10; y = (rho - x* cos(theta) )/ sin(theta); plot(x,y) 回答2: You can just use the built in polar function polar(theta,rho) creates a polar coordinate plot of the angle theta versus the radius rho.

Using GraphicsMagick in Unity3D

阅读更多关于 Using GraphicsMagick in Unity3D

问题 I'm looking for an alternative to using the System.Drawing in Unity3D, since apparently Unity doesn't support it. I'd like to simply draw some lines on a texture. But I want options such as line width and edge rounding, which are fairly complex. GraphicsMagick seemed perfect, plus it's free. So here's the steps I've already taken: 1) I changed my playersettings to use api compatability level 2.0, not "subset". 2) I downloaded GraphicsMagick .Net 2.0 x64 wrapper, extracted the dll. 3) Right

How do I get a JEditorPane to highlight the full width of a line (not just the text)?

阅读更多关于 How do I get a JEditorPane to highlight the full width of a line (not just the text)?

问题 I'm trying to get a JEditorPane to highlight the full width of a displayed line. All the examples I've tried only highlight the textual content. For example if I have content such as this: --------------------------------- |Here is some text | |some more text | --------------------------------- within a JEditorPane represented by the box above, then highlighting the first row highlights only the 'Here is some text' (represented between [ and ] below). --------------------------------- [Here

Python: “Print” and “Input” in one line [duplicate]

阅读更多关于 Python: “Print” and “Input” in one line [duplicate]

问题 This question already has answers here : Possible to get user input without inserting a new line? (7 answers) Closed 3 years ago . If I'd like to put some input in between a text in python, how can I do it without, after the user has input something and pressed enter, switching to a new line? E.g.: print "I have" h = input() print "apples and" h1 = input() print "pears." Should be modified as to output to the console in one line saying: I have h apples and h1 pears. The fact that it should be
