Trying to make a flash light application, I am not getting it working. This is my code:
public void setFlash(Controllable player) {
FlashControl flashControl =
(FlashControl) getControl(player, "javax.microedition.amms.control.camera.FlashControl");
if (flashControl != null) {
int[] supportedFlash = flashControl.getSupportedModes();
if (supportedFlash != null && supportedFlash.length > 0) {
for (int i = 0; i < supportedFlash.length; i++) {
if (supportedFlash[i] == DESIRED_FLASH) {
try {
flashControl.setMode(DESIRED_FLASH);
} catch (IllegalArgumentException iae) {
// continue
}
break;
}
}
}
}
}
According to JSR 234 documentation FlashControl has six public constants:
AUTO: The camera will autoflash according to the lighting condition
AUTO_WITH_REDEYEREDUCE: The camera will autoflash according to the lighting conditions and if it flashes it will use red-eye reduction
FILLIN: Reduced flash
FORCE: Camera flash is on
FORCE_WITH_REDEYEREDUCE: Camera flash is on and red-eye reduction is in use
OFF: Camera flash is off
You should use FORCE or FORCE_WITH_REDEYEREDUCE

Ive been trying to make an RPG game on SFML and now Im kind of struggling on the collisions. My problem is quiet simple, I have this 2 layers, Background and Foreground. Background just acts as a background image and Foreground png image is supposed to act as the collisions, having the part where the character is supposed to walk completely free (transparent) and keeping the rest of the structures to use as collisions (Background image here: https://imgur.com/gallery/DA3zGtD Im making the floor transparent while keeping the rest). Ive tried using the getGlobalBounds().intesect with the character sprite without any succes. I wanna keep it as simple as possible, here is what I have until now:

I think whats happening is that when I want to do the if it takes the whole png instead of just the parts I want as collision. I also wanted to try color collision but I really dont know how to implement it, Im kind of new to SFML. Thanks in advance!
If you wish to have proper collision detection between the player and other objects .intersect() is not good enough. It will either make your character permamently stuck in the structure or make it pass through it without player control, which depends on what behavior you code for this condition.
What would work is detecting from which direction the player is approaching the object, and based on that either make him be moved back a bit or set the speed to 0 if current velocity would take him deeper into the structure.
For example, using intersect() as you are, for case of player colliding with a wall from the left:
if(velocity.x > 0 && player.getLocalBounds().intersect(wall.getLocalBounds()) && player.getLocalBounds().left > wall.getLocalBounds().left)
Then you can use this condition to either stop the player (set the velocity.x to 0), set reverse it so he backs off or do any other kind of behavior you'd wish in the event of a collision.
(Note this is not an ideal solution, but it should work and follow similar logic you've implemented.)
I'm having a lot of trouble with playing audio clips. I suspect it has something to do with update playing my clip from the start every time it executes the block of code that sends the clip to the audio source. Below is a 'solution' but the fact that it works doesn't even make sense to me. If I just put the audio.play() in the main if statement without checking whether it's less than the audio clip length, I hear nothing but a quiet distortion.
void Update()
{
switch(weatherState)
{
case WeatherStates.Sunny:
break;
case WeatherStates.Rain:
Rain();
break;
case WeatherStates.Snow:
break;
case WeatherStates.ThunderStorm:
break;
}
}
void Rain()
{
if(timeScript.hourOfWeatherEvent != 0)
{
if(timeScript.hourCount >= timeScript.hourOfWeatherEvent)
{
rain.SetActive(true);
if(soundCount < weatherSounds[0].length)
{
soundCount++;
audio.clip = weatherSounds[0];
audio.Play ();
}
timeScript.durationOfWeatherEvent -= Time.deltaTime * timeScript.timeSpeed;
if(timeScript.durationOfWeatherEvent <= 0)
{
rain.SetActive(false);
timeScript.durationOfWeatherEvent = 0;
timeScript.hourOfWeatherEvent = 0;
weatherState = WeatherStates.Sunny;
}
}
}
}
I can't seem to find the property for the MediaCapture class that allows me to detect the front camera and switch to it if available. Here is my current setup of the device, it all works as expected on Windows (front cam) and Phone (rear cam). None of the Microsoft samples show the front camera being used in Universal or WP 8.1 (WinRT/Jupiter).
mediaCaptureManager = new MediaCapture();
await mediaCaptureManager.InitializeAsync();
if (mediaCaptureManager.MediaCaptureSettings.VideoDeviceId != "" && mediaCaptureManager.MediaCaptureSettings.AudioDeviceId != "")
{
StartStopRecordingButton.IsEnabled = true;
TakePhotoButton.IsEnabled = true;
ShowStatusMessage("device initialized successfully!");
mediaCaptureManager.VideoDeviceController.PrimaryUse = CaptureUse.Video;
mediaCaptureManager.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
mediaCaptureManager.SetRecordRotation(VideoRotation.Clockwise90Degrees);
mediaCaptureManager.RecordLimitationExceeded += RecordLimitationExceeded;
mediaCaptureManager.Failed += Failed;
}
There is a sample on the Microsoft github page that is relevant, although they target Windows 10. Still, the APIs should work on 8/8.1.
UniversalCameraSample: This one does capture photos, and supports portrait and landscape orientations. Here is the relevant part:
private static async Task<DeviceInformation> FindCameraDeviceByPanelAsync(Windows.Devices.Enumeration.Panel desiredPanel)
{
// Get available devices for capturing pictures
var allVideoDevices = await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture);
// Get the desired camera by panel
DeviceInformation desiredDevice = allVideoDevices.FirstOrDefault(x => x.EnclosureLocation != null && x.EnclosureLocation.Panel == desiredPanel);
// If there is no device mounted on the desired panel, return the first device found
return desiredDevice ?? allVideoDevices.FirstOrDefault();
}
And you can use it like so:
// Attempt to get the front camera if one is available, but use any camera device if not
var cameraDevice = await FindCameraDeviceByPanelAsync(Windows.Devices.Enumeration.Panel.Front);
if (cameraDevice == null)
{
Debug.WriteLine("No camera device found!");
return;
}
// Create MediaCapture and its settings
_mediaCapture = new MediaCapture();
var settings = new MediaCaptureInitializationSettings { VideoDeviceId = cameraDevice.Id };
// Initialize MediaCapture
try
{
await _mediaCapture.InitializeAsync(settings);
_isInitialized = true;
}
catch (UnauthorizedAccessException)
{
Debug.WriteLine("The app was denied access to the camera");
}
catch (Exception ex)
{
Debug.WriteLine("Exception when initializing MediaCapture with {0}: {1}", cameraDevice.Id, ex.ToString());
}
Have a closer look at the sample to see how to get all the details. Or, to have a walkthrough, you can watch the camera session from the recent //build/ conference, which includes a little bit of a walkthrough through some camera samples.
Here is how to get the device's available cameras and set the front one for the stream:
mediaCaptureManager = new MediaCapture();
var devices = await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture);
var deviceInfo = devices[0]; //grab first result
foreach (var device in devices)
{
if (device.Name.ToLowerInvariant().Contains("front"))
{
deviceInfo = frontCamera = device;
hasFrontCamera = true;
}
if (device.Name.ToLowerInvariant().Contains("back"))
{
rearCamera = device;
}
}
var mediaSettings = new MediaCaptureInitializationSettings
{
MediaCategory = MediaCategory.Communications,
StreamingCaptureMode = StreamingCaptureMode.AudioAndVideo,
VideoDeviceId = deviceInfo.Id
};
await mediaCaptureManager.InitializeAsync(mediaSettings);
You'll need to consider rotation because front and rear cameras on different devices have different rotations, but this will initialize your MediaCapture properly
i want to use a container view in story board project with mono touch and i don't know good objective c have a lot of sample but i couldn't understand.
thanks a lot
i have 4 view controller on my project and one customseque
i don't know how to call first view controller in main view controller
i try to put some codes in container view controller but couldn't success please help me from where i have to call and which code will call it - please xamarin code ..
i solved my problem like this.. thanks by the way who is viewed this question..

I have a simple text editor that I created in Visual Studio 2010 Professional Edition. Basically I modified the MFC MDI program automatically generated by the VS2010 wizard. The problem is that when i print, it gives me a debug assertion error in viewrich.cpp line 294. I have not modified anything in the code to do with printing, though it could be something wrong with how i used Rich Edit. This is all the information I have. Thanks in advance.

The ASSERT says it all:
UINT nPageSave = pInfo->m_nCurPage;
ASSERT(nPageSave > 1);
This is a value for the current page to print/paginate. It is set to 1 in CPrintInfo's constructor. But something changed it and made it 0 or negative. Usually this value is completely controlled by the RTF printout. So you must done something that manipulates it.
You have to set the Minimum page and the Maximum page value (SetMinPage and SetMaxPage) in CPrintInfo.
