When I try to display him in the same method with which I displayed the background, he doesn't appear unless I slightly manually alter the size of the Jframe. And even then when he appears there's a small white square in the bottom right corner of his image. What can I do to fix this? Is there any other way I can insert the

I found a lot of references to the AI of the ghosts in Pacman, but none of them mentioned how the eyes find their way back to the central ghost hole after a ghost is eaten by Pacman. In my implementation I implemented a simple but awful solution. I just hard coded on every corner which direction should be taken. Are there any better/or the best solution? Maybe a generic one that works with different level designs? Kylotan Actually, I'd say your approach is a pretty awesome solution, with almost zero-run time cost compared to any sort of pathfinding. If you need it to generalise to arbitrary

For python 2, you should be able to use this command to install using pacman: pacman -S python2-scikit-learn Make sure the package name has the number "2" in it. As per scikit-learn's installation guide , another way to install it is using pip: pip install --user -

VMware虚拟机上运行Manjaro系统

Manjaro系统是从ArchLinux系统发展而来。它的软件安装工具不是ubuntu的apt-get,不是yum,而是pacman。 在虚拟机安装好Manjaro后, 安装虚拟机工具VM-Tools 重启后即可在虚拟机与主机之间复制粘贴,可以设置1920*1080的分辨率显示屏了。 #安装open-vm-tools软件 pacman -S open-vm-tools #安装依赖 pacman -S gtkmm pacman -S gtkmm3 #重启 reboot 来源: https://www.cnblogs.com/charleechan/p/11673206.html

manjaro安装及设置

因我的笔记本(联想的拯救者)昨晚打开后什么都还没做就被更新系统“抢走”了画面导致按什么都不管用 所以就想起能不能不用win系统,都知道linux比win稳定,so....就找到了manjaro。以下是安装方法和部分设置(安装过程中部分步骤略过,请注意) 下载地址: http://iij.dl.osdn.jp/storage/g/m/ma/manjaro/xfce/17.1.7/manjaro-xfce-17.1.7-stable-x86_64.iso 转载请注明出处 U盘启动用Win32DiskImager,使用软碟通做u盘启动时会报错,以下安装方式是在虚机上安装: 正常启动起来的画面(以下画面是经过部分设置后的效果): 设置部分: 更换软件源: 编辑nano /etc/pacman.d/mirrors, 在最上方添加两行源地址 ## 阿里云 Server = http://mirrors.aliyun.com/archlinux/$repo/os/$arch ## 清华大学 Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch 保存设置方法: 用nanoc编辑好文本后按trl + x 然后按y再按回车即可。另外manjaro中的pacman相当于centos(或redhat)中的yum命令
