QUESTION
I would like individual cars to drive across the screen from left to right with a certain time interval.It should be an endless loop. It is ended by program end With my code, they all start at the same time. In addition, rect.y changes from the default value 300 to 0.
...ANSWER
Answered 2022-Jan-13 at 08:56(Assuming you want these cars to be robots) First create variable and lets name them car_move_right
and car_move_left
. If you want the car to move towards the right at the beginning of the game, set the car_move_right
to True and the other variable to False, and vice versa. Then in the main loop, add an if
statement like this:
(Taking carX to be X-coordinate of car)

I'm trying to take a screenshot of my WebGL app but the results are not right.
Running puppeteer in headful mode works just fine but I need it in headless mode.
I've hosted my shader on shadertoy to make things easier here.
The shader is really simple, it uses a PRNG to draw a starfield.
Puppeteer version: 7.0.1
Chromium version: 90.0.4403.0
Here is my shader:

QUESTION
I created a star plotting application to plot labels for a 3d star plotter so that the labels are mapped local to scene. I wanted to do this so that whenever I rotate the starfield, the labels are always facing forward and don't rotate with the individual stars (annoying because they can't be read).
Now this works very well until I added a control panel above it. In the application below, if the control panel is not present, then labels track with the position of the stars. But with the control panel, the labels are y-offset by the size of the control panel height.
The issue is that the "mousePosY = me.getSceneY();" returns the mouse position of the scene itself and not the defined subScene. I had thought that the "subScene.setOnMouseDragged((MouseEvent me) -> {" would have given me the position of the mouse relative to the subScene and not the scene.
Is there any way to fix this so that the returned X,Y position is for the subScene only?
The following code is a very cutdown version of my application that shows the actual issue itself.
...ANSWER
Answered 2020-Nov-03 at 16:29I broke this down into a simpler problem relating mouse offset, solved that, and then worked that solution into here.
The key issue is that I assumed that the mouse event (x,y) positions would be zero offset to the SubScene, and in reality, they are relative to the containing scene. I had to calculate the bounds of the component relative to the parent. Having the actual location of the SubScene in the layout of the larger application allows me to calculate the corrected (x,y) positions.
Here is the answer:

QUESTION
Trying to create a space background for a simple browser game we are running into trouble with the canvas only painting in the top left quadrant.
This is a React app using Emotion as CSS in JS. We are trying to set the canvas dimension via its width and height property to rely on this for painting. Then we want to use CSS injected through emotion to resize the canvas to fit its containers width while maintaining aspect ratio.

The component in question looks like this:
...ANSWER
Answered 2020-Sep-03 at 21:16You're accessing the offsetHeight and width of the canvas element which is how much space the canvas takes up not the size of the canvas. What you should be basing your random calculation on is the width and height of the canvas. Changing maxWidth and height to the following will base your numbers off the canvas dimensions not the dimensions of the canvas element in the DOM.
