I am doing a dig the mud game. Have 2 mud gameobject(sprite) that need to dig in the correct order. I assign one script for each object. Disable mud2 boxcollider to prevent them from moving until mud 1 is drag to trigger L box collider . But when I try playing, mud2 still can be drag even though mud1 havent trigger L box collider. I also untick the box collider of mud2....

You could try the Destroy(object, time) method instead of disabling colliders
I'm using the MVVM pattern, I have the mouse position on my
Plot in my model through the attachment to a mouse behaviour.
I am using a
DateTimeAxis for the x-axis, I would like to get the x-axis value from my x-position, but I don't know how to proceed.
If I was not using the MVVM pattern, a good way of accomplishing what I want, would be:

I do not know where you got the
MouseBehavior from, but it might be incompatible with
Plot. I think the easiest way is to create your own behavior that fits your requirements, since you already have a working code-behind solution. If you translate it into a behavior, it would look like this.
I am trying to select multiple features in a feature layer by using "hold 'ctrl' button and mouse click event". I am using ArcGIS JS API 3.x.
I have created the US State boundary FeatureLayer by using FeatureCollection and able to display the layer on map. User wanted to select multiple states by mouse click while holding 'ctrl' or 'alt' key....

It's been a long time I do not work with 3.xx API. Anyways maybe this example that I made for you can help you. The idea is basically listen to click events on the feature layer to catch selected graphics and then added to selected collection. When adding just check if the desire keys are pressed.
I want to use RX to enable mouse dragging behaviour to select areas in a plot. (Oxyplot) It should be possible to select multiple areas in a plot and their should be a live update of the select area.
So far i have set up three observables from events:...

I think you're overthinking things a bit.
Here's the query you need:
I Can't get values from variable(Vector2).
My goal is send float variable from PlayerAttack to PlayerAttacking....
ANSWERAnswered 2020-Aug-30 at 17:45
The problem occurs when you call
FindAttackAngle(_attackangle) The reason is that
Vector2 is a structure, not an object. You can read about the difference between passing structures as parameters versus passing objects as parameters here
The TLDR version of that linked article is that if you pass a structure variable into a method, it is passed by value. That means that if you change the structure's fields inside the method, the structure will still have its original values outside of the method. Objects, by contrast, are passed by reference, which is why changes to their properties inside the method will be reflected outside the method (which is what you're expecting to happen).
To fix this, specify that you want to pass by reference like this:
I know we can get the

You can get the
CoordinateFormatter as below
I'm using the script below to move an object (on X and Z axis) smoothly with mouse movement, it works perfectly on the world's axis, I mean when the object's rotation is (0,0,0).
But how can I make the object move on its local axis (I mean when its X rotation is -20, its Z movement should be progressive)?
ANSWERAnswered 2020-Jun-15 at 15:55
Okey I found the answer, and it was simple:
- Create an empty gameobject and make it the parent of the moving object.
- Apply the rotations to the parent, so the child has no rotations.
- Attach the code to the child, but use "transform.localposition" instead of "transform.position".
I want to see all the features in a graphicsLayer that match an x,y from a mouse. The hitTest() method works for the topmost one:...
ANSWERAnswered 2020-Apr-27 at 03:40
In the new version of the API, 4.x, what usually was a the
GraphicLayer purpose (handling client side features) became part of
FeatureLayer or other layers like
Now, the recomendation is to use
It is generally preferred to construct a FeatureLayer with its source property when working with client-side graphics since the FeatureLayer has more capabilities than the GraphicsLayer, including rendering, querying, and labeling.
In regard to visualization, your could use clustering on
