You should not be drawing on the Form's Canvas from outside of its OnPaint event at all. All of the drawing should be in the OnPaint event only. Have your timer save the desired information into variables that the Form can access, and then Invalidate() the Form, and let its OnPaint event draw the image using the latest saved information.

Alternatively, simply display your BMP inside a TImage control, and then have the timer set that control's Left/Top/Width/Height properties as needed. Let the TImage handle the drawing of the image for you.

Using Math.random() method i created 2 values and adjusted them accordingly , inorder to make them more sensible ( not moving outside div element ). After that i used setInterval method and stored it in global variable to set it again or clear it using clearInterval method. Finally created moveAtSpecifiedPos function helps you to set the position when it is clicked

Change the attributes of the div with class ball to figure out animation speeds and smoothness ! One thing I really was not able to figure out how to make collision at right time using js

Use pygame.time.Clock to control the frames per second and thus the game speed.

The method tick() of a pygame.time.Clock object, delays the game in that way, that every iteration of the loop consumes the same period of time. See pygame.time.Clock.tick():

This method should be called once per frame.

e.g.:

I suggest you to use Cinemachine for this. You can make a very comfortable setting with VirtualCamera. Smooth transitions, distance tracking, rotation tracking etc. Everything is pretty easy. https://unity.com/unity/features/editor/art-and-design/cinemachine

That is because your condition in if statement is always true. Since "h" is in or (||).

Instead use:

Don't put single quotes around the table and column names:

The performance problem is probably not related to the actual filtering, 2000 items are not a lot and should probably be within a millisecond or so. However, await Task.FromResult seem really odd, this will not do anything asynchronous at all, and should probably just be removed altogether, synchronous filtering should be enough unless you have one or more magnitude more items. Also, you are calling Search.Text.ToLower() repeatedly without reason.

I would suspect repeated calls to SearchableImages.Add(p) that trigger UI updates etc to be the main issue. As always with performance, measure and/or profile to be sure.

To solve this I would suggest taking a look at CollectionView that has an explicit Filter property you could use. See also: Filter an observable collection

The reason why toEqual doesn't work for your assertion, is because even though the objects mockEmpOut and component.testVar are "equal", they are NOT "the same", since they represent objects that live in different locations in memory. toEqual returns false if the object references belong to two different objects in memory.

The minute we write the below statement, it creates a new object in memory.

You can use Mathf.PingPong to go back and forth between 2 values.
