  • how to stop enemies from moving to one point when lots of them are chasing one object [duplicate]

    - by BBgun
    This question already has an answer here: Is there a simple way to stop enemies standing in the same spot? 8 answers i am making a top down game which lots of enemies are chasing one guy. then,enemies would move to one point without any collision,they just overlay each other. so ,is there any simple way to make them feel more real? make them not overlay with each other? ================================= i have tried the solution using boundbox to check collision, but i still very puzzled about what to do with the collision. i have a bad solution.it doesn't work well. my solution in simple: foreach(around_enemy_arr in other) { vector a = normalize(self.positionvector - other.positionvector); self.move_vector = self.move_vector + a; } this can work,but when plenty of enemies come very close to each other,they would shake. i am sooooo confused. please help.

  • Add closure after concatenating files or keep one for each separate file?

    - by sdespolit
    At the moment every javasrcipt file in our project includes closure wrapper. Before deploying all files are concatenated and minimized. And i'm asking myself, do we really need all that closures OR one closure added after concatenation will do the job. I can see only one reason not to do that - the variable we are sharing between files will get in the global namespace. But there is no conflict so is don't see any problem. The real question is what other cons may be? Or more generally what approach is better - one closure or many?

  • What can I do to make my eService website customers feel it is a luxurious service? [closed]

    - by Farshid
    I'm developing an e-service website that its monetization model is via paid membership. Beside quality service and content, because I'm serving them for a high fee, I want to make them feel like it is a personal, unparalleled kind of service and I want to spend money for creating things that I give them after their registration such as a beautiful physical membership card so that I can use the effect of mouth-words better and beside that let them be proud about the service. I've tried my best to develop the site experience classy and I'm looking for things in real world to send them after their registration (such as membership card and a small paper tutorial). What are your suggestions? Have you seen things like this before that a website sends you some physical things for making you more loyal and/or something like that? Please kindly share your experiences/suggestions.

  • C# .NET 4.0 interactive course?

    - by Kanyhalos
    I would like to learn C# programming. I already studied it for several weeks and wrote some minor programs with VS2010, and I'm not completely newbie at programming because I worked on STALKER - Shadow of Chernobyl as scripter, but it was LUA. I want to become a real programmer. I think C# is a decent way to start with. I already learned about the most commonly used resource sites and got some nice eBooks as well, but unfortunately I don't have time to sit down in front my computer all the time, so my progress is pretty slow. I would like to ask that if someone can recommend me some decent interactive online courses to make my learning progress faster. I know about the "joe grip" course but I don't know if it's worth $39 also it's only for .NET 1.x and 2.0 while I'd like to learn 4.0 so I have no idea what should I do.

  • Issue with div image size [migrated]

    - by nextyear
    I hope this helps explain the issue I am having I have recently designed a horizontal scrolling portfolio for a client, the rights and wrongs of horizontal web design, is a sligtly seperate topic but alas the client wanted something different. Im having a real issue with the bottom div though As the monitor size is reduced its creating the browser scroll bar down the side as the div image is overlapping the monitor size. Wouldnt be such a huge issue but because of the nature of the horizontal site its producing a diagional scrolling effect. Is there away to prevent the screen expanding from the actual monitor size using css or anyother solution? I'm probably staring at the answer as I type but brain doesnt seem to be working unfortunately.

  • Display settings problems with Ubuntu 14.04 LTS

    - by DontUSASme
    For whatever reason (this was working correctly on Ubuntu 12.04 LTS) when I try to set my displays on top of each other in the settings, it won't allow to place them on top of each other. When I click "apply" I get the error message "Could Not Set Configuration Mode for CRTC 63." Can anybody help me with this? It wont let me set the two displays on top of each other, but it will allow me to place them side to side. Also, I get a random "Unknown display" as well. This was not existent in 12.04 LTS and I have no idea what it is, seeing as how the only screens that are in use, or plugged up for that matter, is my laptop's display (1366x768) and my Samsung TV display (1360x768) thru HDMI.

    - by Tony
    I was unsure on where to post this question so I am posting here. I was wondering if any of you are using one of the new windows 8 convertible tablets to do web development on? If so what model are you using and how do you find the experience? I have a monster gaming laptop that I usually use to develop on but it is so large and is a real pain to move around with. I would like something that is extremely portable and would effectively let me develop anywhere.

  • Can't boot after disk error 12.10

    - by user1189907
    Lately, I've been having Ubuntu crashing randomly.. it goes into read only mode, but once I restart it's working again. Today it happened again and I had to manually shut the computer down. Now I'm not able to boot anymore. I get the following when turning the computer on: error: unknown filesystem And I'm left at "grub rescue". I booted from the Live CD and installed "boot-repair". When I run it it says "no os has been found on this computer", it gives me no option to carry out any fixes. Boot Repair generated the following output which shows some errors: http://paste.ubuntu.com/1348224/ Any idea on how to fix this?

  • permanently disable bluetooth

    - by NotABluetoothUser
    I simply don't use bluetooth. Since it can be a security risk and also drains the battery I would like to keep it deactivated. I quickly found the option to turn it off in the settings menu, but the problem is: it doesn't stay dead! Everytime I pull my Nexus 4 out of standby mode bluetooth reappears in the top bar as if I never deactivated it. How can I deactivate it so it stays deactivated or better yet how can I remove it from my phone entirely? I tried sudo apt-get remove bluez bluetooth, but I am not allowed to edit this package.

  • How many LOC/day "top" (google, MS, FB) engeneers produce? [closed]

    - by NoSenseEtAl
    I know that 25 lines of lock free code is harder to do than 1000 lines of On_Click()... code but I wonder does anybody know in general what is the productivity of the average programmer in top tech companies. Motivation: I often go ??? mode when I see how low LoC/ day i produce(Im new to the my current language and Im part of the big project, but still..) and I would like to know how bad I am. :) If you are gonna warn me that LoC is a terrible measure I agree, but it is most exact one in a sense that I cant go and write 0.01% of Chrome or IE and say it took me this long so....

  • Getting URLs from search results

    - by tereško
    After 1 months research I basically give up on getting all URL's from a search results programmatically, I looked at Google Search API to find a way to get millions of search results "URL's" to be specific to a text file or something relative but no success, but I am 100% there must be a way or trick of doing it. Real Question : Is there anyway programmatically or manually I can get 1000+ search results (URLs using search query e.g. "Apple" returns million of results on google and I want as much as possible URLs of them results in a text file) Note : Don't care for any specific search engine or programming language or technique or software or just point me to right direction, but yeah I tried it with google API i can't get more then 100 results at all.

  • Laptop Hibernates after adapter is unplugged

    - by SpyrosR
    Hello i am experiencing a strange problem under Ubuntu 12.04. If I unplug the charger while my laptop is on,i don't see any messages but my laptop goes straight into a suspend or hibernate mode and it's a real pain to get it stable again afterwards. It always suspends (or hibernates) It always takes 2 attempts to restart it (press power button, it starts and it hibernates again, press power button and it starts and stays on) It sometimes has an effect on the wireless which doesn't come back clean and i either have to switch the wireless on and off a couple of times. I sometimes have to restart the laptop totally Is anyone else experiencing the same issues and if yes,is there any solution? Thank you in advance.

  • is it valid that a state machine can have more than one possible state for some transition?

    - by shankbond
    I have a requirement for a workflow which I am trying to model as a state machine, I see that there is more than one outcome of a given transition(or activity). Is it valid for a state machine to have more than one possible states, but only one state will be true at a given time? Note: This is my first attempt to model a state machine. Eg. might be: s1-t1-s2 s1-t1-s3 s1-t1-s4 where s1, s2, s3, s4 are states and t1 is transition/activity. A fictitious real world example might be: For a human, there can be two states: hungry, not hungry A basket can have only one item from: apple, orange. So, to model it we will have: hungry-pick from basket-apple found hungry-pick from basket-orange found apple found-eat-not hungry orange found-take juice out of it and then drink- not hungry

  • Which should I use for mouse over tooltip for image (alt, longdesc, title)

    - by Virtual Jasper
    Currently, my webpage images use the alt attribute only. Users complain that their IE8 cannot show the "tooltip" bubble when they mouse over the image. On Microsoft's What's New in Internet Explorer 8 page, it says The alt attribute is no longer displayed as the image tooltip when the browser is running in IE8 Standards mode. Instead, the target of the longDesc attribute is used as the tooltip if present; otherwise, the title is displayed. The alt attribute is still used as the Microsoft Active Accessibility name, and the title attribute is used as the fallback name only if alt is not present. I also found that many say title should be used. Which should I use to meet the industrial standard: alt, longdesc or title?

  • Recommended Books for OpenGL [closed]

    - by TheBlueCat
    I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?
