QUESTION

Camera on transporter of population

Asked 2022-Feb-09 at 19:18

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

Just put the camera into your AGV agent type. Make sure that your TransporterFleet is adding new transporters to a custom population of AGV agents (myPop), see below:

In your model, you can now change the camera using my3DWindow.setCamera(((AGV)randomFrom(myPop)).myCamera);

ANSWER

Answered 2021-Dec-18 at 22:39

Better 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.

Zoom out camera while keeping text locked - Phaser 3

Asked 2021-Nov-27 at 15:54

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 15:54

Thanks 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.

ANSWER

Answered 2021-Nov-18 at 12:41

You 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.

Install image_projection

If you haven't already installed it, install ROS. Please use Desktop-Full Install to run the demo. Noetic is officially supported, but Melodic and Kinetic should work as well. Create a new catkin workspace. Skip this step if you use your existing workspace. Go into the source directory of your workspace and check out image_projection. Install dependencies via rosdep and wstool (.rosinstall). and source the workspace. Verify your installation by launching the demo (see below).
To use image_projection for your robot, you will need to update camera topics, calibration and projection parameters. You can duplicate the launch and configuration files in the demo and adapt them to your robot. The main launch file is image_projection_demo/launch/projections.launch. It loads the configuration, calibration and starts up the projection nodelets. Cameras are configured in image_projection_demo/config/camera360_cameras.yaml. This setup uses an extended camera calibration from kalibr. Projections are configured in image_projection_demo/config/projections.yaml.
