question:как в unity получить время через которое закончится анимация?
answer:В Unity, чтобы узнать время до окончания анимации, вы можете использовать `Animator` компонент, который управляет анимацией. У этого компонента есть несколько полезных функций и свойств, которые позволяют вам получить длительность анимации и текущую позицию воспроизведения. Чтобы узнать оставшееся время анимации, вам нужно будет выполнить некоторые расчеты. Вот как вы можете это сделать: 1. Получите ссылку на `Animator` компонент вашего объекта. 2. Активируйте анимацию, если это еще не сделано. 3. Используйте `GetCurrentAnimatorStateInfo` для получения информации о текущем состоянии анимации. 4. Используйте свойства `length` и `normalizedTime` для расчета оставшегося времени. Вот пример кода, который можно использовать в скрипте Unity: ```csharp using UnityEngine; public class AnimationTimer : MonoBehaviour { private Animator animator; void Start() { animator = GetComponent<Animator>(); // Запустите вашу анимацию здесь animator.Play("YourAnimation"); } void Update() { AnimatorStateInfo animationState = animator.GetCurrentAnimatorStateInfo(0); float timeLeft = animationState.length - (animationState.normalizedTime % 1) * animationState.length; Debug.Log("Время до окончания анимации: " + timeLeft); } } ``` Пояснение к коду: - `GetCurrentAnimatorStateInfo(0)` возвращает информацию о текущем состоянии анимации для слоя номер 0 (в Unity могут быть разные слои анимации). - `animationState.length` - это длительность анимации в секундах. - `animationState.normalizedTime` - это нормализованное время проигрывания анимации, где 1.0 означает, что анимация прошла один цикл полностью. Заметьте, что это значение может быть больше 1, если анимация проигрывается в цикле. - `(animationState.normalizedTime % 1)` - получаем дробную часть нормализованного времени, что даёт прогресс текущего цикла анимации. - `(animationState.normalizedTime % 1) * animationState.length` - расчет времени, которое уже прошло в текущем цикле. - `timeLeft` - оставшееся время до конца анимации. Обратите внимание, что если анимация зациклена, то `normalizedTime` будет увеличиваться бесконечно, и вам, возможно, потребуется другой способ определения конца анимации в зависимости от вашего варианта использования.
question:Fix this command: adb shell 'while :; do ! ps -A | grep frida-server > /dev/null && echo "Restarting Frida" && /data/local/tmp/frida-server & sleep 60; done'
answer:The command you've provided is meant to run a loop on an Android device using ADB (Android Debug Bridge) to check if `frida-server` is running; if it's not, it will print "Restarting Frida", start `frida-server`, and then wait for 60 seconds before checking again. However, there is an issue with the use of the `!` in the `do` loop. Here's the corrected command: ```sh adb shell 'while :; do ps -A | grep -q frida-server || (echo "Restarting Frida" && /data/local/tmp/frida-server &); sleep 60; done' ``` Changes and explanation: 1. Replaced `! ps -A | grep frida-server > /dev/null` with a more readable `ps -A | grep -q frida-server ||`. The `-q` flag for `grep` makes it quiet (no output), which is effectively like redirecting to `/dev/null`. The `||` means that the following commands will be executed only if `grep` doesn't find `frida-server` (i.e., it exits with a non-zero status). 2. Removed the `!` operator preceding the `ps` command. It was negating the result incorrectly. 3. Enclosed `echo "Restarting Frida" && /data/local/tmp/frida-server &` in parentheses to ensure that the echo and the frida-server restart command are considered a single unit for the condition. 4. The `&` after `/data/local/tmp/frida-server` is kept to run `frida-server` in the background. After running this command, your ADB shell will enter a loop that checks if `frida-server` is running every 60 seconds, and if it's not, it will print "Restarting Frida" to the shell, start `frida-server` in the background, and then sleep for 60 seconds before checking again.
question:) was unexpected at this time.
answer:Apologies for the confusion. It looks like there is an issue with the command syntax for the shell invoked by `adb`. When using adb shell with a while loop, you should take care to escape certain characters and ensure the syntax is compatible with the shell used on the device (typically `sh`). Let's fix the command accordingly: ```sh adb shell 'while true; do ps -A | grep -q frida-server || (echo "Restarting Frida"; /data/local/tmp/frida-server &); sleep 60; done' ``` Or you can use escaped characters to avoid issues with parentheses: ```sh adb shell 'while true; do ps -A | grep -q frida-server || { echo "Restarting Frida"; /data/local/tmp/frida-server & }; sleep 60; done' ``` Here's a breakdown of the corrected command: 1. `while true` is another way to write `while :` and represents an infinite loop. 2. `ps -A | grep -q frida-server` searches for `frida-server` among the running processes. The `-q` flag tells `grep` to be quiet and just return an exit code. 3. The `||` operator is a logical OR that will execute the following command block only if the previous command (the `grep`) fails to find `frida-server`. 4. `{ echo "Restarting Frida"; /data/local/tmp/frida-server & }` is a group of commands. First, it outputs the message, then starts `frida-server` in the background. 5. `sleep 60;` pauses the loop for 60 seconds before it runs again. 6. The whole command is single-quoted to be passed as a single argument to `adb shell`. 7. If you encounter issues with the curly braces `{` `}`, you can also try using parentheses, but the `&` after frida-server may need to be escaped (as in the first version). Make sure the frida-server binary at `/data/local/tmp/frida-server` has execute permissions (`chmod +x /data/local/tmp/frida-server`) before running this command.
question:Is grep in adb?
answer:Yes, `grep` is typically available in the shell environment of most Unix-like systems, including many Android devices. However, some Android device manufacturers might ship devices with a shell environment that is more limited and does not include `grep`. For example, on devices with a restricted or minimal set of utilities, you may find that `grep` or other standard Unix tools are not present. If you find that `grep` is not available in your Android shell environment, you have a few options: 1. **Use Toybox:** Modern Android versions come with Toybox, a collection of common Unix utilities combined into a single executable. You can use Toybox commands for similar functionality. For instance, you can use `toybox ps` and `toybox grep`. 2. **Install BusyBox:** You can install BusyBox, which provides implementations of many common Unix utilities like `grep`. BusyBox is designed for embedded systems and is a common addition for rooted Android devices. 3. **Find Alternatives:** You could also attempt to use `findstr` on some devices, which serves a similar purpose to `grep`, or you can use shell-specific constructs to filter process lists instead. Here is an example of how you might rewrite the command without using `grep`: ```sh adb shell 'while true; do for proc in (ps -A | awk '''{print NF}'''); do [ "proc" = "frida-server" ] && break; done; [ "proc" != "frida-server" ] && echo "Restarting Frida" && /data/local/tmp/frida-server &; sleep 60; done' ``` In this example, `awk` is used to extract the last field of each line output by `ps`, assumed to be the process name. The loop checks whether `frida-server` is one of those process names. If not, it proceeds to restart `frida-server`. This is assuming that `awk` is available, which is generally more likely than `grep`. However, if `awk` is also not available, you might need to rely on even more basic shell commands, or consider installing BusyBox or another environment that provides the needed utilities.
