项目基础工程,包含各类底层操作(寄存器方式),但需要移植HAL库形式的操作方式。 1、移植库函数DMA和spblcd 2、移植了gui,并成功运行显示,同时修改了usart的结构(usart的初始化和中断处理均在usart函数中执行) 3、移植了RTC和Calendar,但是在RTC_GetTime函数中,使用库操作方式时读取的hour、min、sec值均不变化,目前暂时先采用可以使用的寄存器方式 4、移植system setting功能,包含各种系统设置,但没有加入timer移植 5、移植了ebook、音乐、时钟、记事本、手写画笔、计算器、9D、水平仪、按键、LED。但音乐和水平仪有一定问题 6、修改工程中使用到原sys.h中端口控制的代码为宏形式,包括lcd.h、ctiic.h、ft5206.h、gt9147.h、ott2001a.h、touch.h、w25qxx.h、nand.h、rtc.h、ov5604.h、sccb.h、ds18b20.h。但修改后工程运行有问题:无法读取字库,无法操作usb盘等 7、修复了步骤6中出现的错误,现在已经回复到步骤5的状况(步骤6主要问题是对HAL_GPIO_WritePin函数的参数GPIO_PIN_X没有传送正确) 8、修复了mpu9250的应用不能使用的问题(重新加入了mpl支持的代码) 9、将timer、ov5640、dcmi、tpad、facereco文件中使用寄存器的地方修改为hal库形式,但若全部开启,则会出现内存不够情况,将timer.c文件屏蔽部分函数,则可编译通过。原因暂时判断为其他文件中变量使用太多了。 10、修复了9中的内存不够bug(在代码中使用到malloc函数的地方修改为申请外部内存),继续修改timer、camera、sccb中寄存器为HAL库形式。 11、优化recorder中的HAL_LIB函数,添加USB模块,但目前无法使PC识别u盘。 12、增加了lwip、webcamera模块,且能正常运行。所有功能模板已经基本添加完成(还缺少SDIO WIFI),现需要对各模板进行hal优化。 13、修改task.c中36行,将OSTaskCreate修改为OSTaskCreateExt后,9D测试功能立即正常使用。 14、修正了水平仪数值不正确,以及跟随不及时情况。(主要修正了t++和continue语句的位置,向外提了一层) 15、修复进入录音功能后系统重启现象(是由于访问越界造成,主要修改了RX_DMA的配置代码) 16、修复了进入usb时系统重启问题(目前的解决办法是将usb连接放在系统启动前即可正常运行,一旦放在系统启动后,还是会重启).

QUESTION
I want to put a camera on a transporter of an agent type AGV. Since there are multiple AGV transporters I cannot simply put it on the agent since it will give errors. So I tried to randomly select an AGV of the population, based on the busy parameter of the AGV agent. But when I try this it gives the next error: AGV can not be resolved to a variable.
AGV is an Agent type in my model and I've created a transporter fleet with as agent type the AGV (I also do not know if this is the correct method).
I've tried to code it in the following manner:
I'm not really sure what I'm doing wrong, but I also could not find any simple example of putting a camera on AGVs or containers or something, only very complex examples or examples where there was just one agent (e.g. an airplane).
Later added:
Thanks in advance, Aron

QUESTION
How to create collisions for a flying camera in Unity 3d? to prevent the camera from falling into objects on the scene. My camera script snippet:
...ANSWER
Answered 2021-Dec-18 at 22:39Better put you camera movement in the LateUpdate()
as adviced in the docs.
With a rigidbody and a collider properly set for the collision detection. Check docs so that you can detect the collisions properly.
Check that " Notes: Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached", so your camera could be one gameObject with no rigidbody, so that you can fly free and collide.
I case you might need physics behaviour for yout camera and you want it also to behave as a rigidbody I would set the camera movement with rigidbody.SetPosition instead of with transform.position = new Vector3()
, as you need to choose to set the transform in the geometric or the physics world.
Also you would need to uncheck the gravity option not to fall.

QUESTION
I'm making a sword game in which you have to collect coins to get big and you fight people. Here's what I have so far:
Notice how the player gets bigger as it collects coins. After a while, you get so big that you cover the entire screen.
I realized I have to zoom out the camera based on the players size.
This is what I have for camera (in create function)
this.cameras.main.startFollow(this.mePlayer);
I added this line of code before it:
this.cameras.main.setZoom(0.5)
Now it turns like this. The text is all smaller and for some reason my tileSprite background breaks too.
Here is the code for the text.
...ANSWER
Answered 2021-Nov-27 at 15:54Thanks to samme for helping me solve this.
In the end I created another camera called UICamera.
I used the ignore
function to ignore all of the game objects on that camera.
And I ignored all the text, minimap, ui, and tilesprite background on the main camera.
Then, to zoom out, I would just zoom out the main camera and adjust the tileSprite scale manually.

Based on the link provided above, does Safari 15 support getUserMedia? I trying use it to access camera, when I test it on safari 15 it asked camera permission, after I allow the permission it still show me nothings. The link show Safari 15 is support getUserMedia/Stream API but not support Navigator API: getUserMedia. Below is my code, which one I should refer to? getUserMedia/Stream API or Navigator API: getUserMedia
...ANSWER
Answered 2021-Nov-18 at 12:41You definitely want navigator.mediaDevices.getUserMedia()
method. It definitely works on iOS. The other one is deprecated. Apple is so late to the getUserMedia() party that they did not implement the deprecated API.
You can read about viewing the iOS console. You need to connect your iOS device to a mac, then use the Safari on that mac, to do that. It's a pain in the xxx neck. Explaining how is beyond the scope of a Stack Overflow answer.
Or you can use alert()
for debugging.
You need to call cameraView.play()
at the right moment. Here's the documentation.
It recommends doing something like this.
