When you make a game, you often need to make enemies that move towards the player.

And here is the script used on this video:

using UnityEngine;

public class enemymover : MonoBehaviour {

	}
	
	// Update is called once per frame
	void Update () {
        //transform.LookAt(player.transform);
        Quaternion targetRotation = Quaternion.LookRotation(player.transform.position - transform.position);
        transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, 1 * Time.deltaTime);
        transform.position += transform.forward * 1f * Time.deltaTime;
	}

How to disable “Authentication Required” or “Sign In” Pop Up in wp-admin

Sometimes when I tried to login to my WordPress websites I see a popup asking me to sign in. Well, I tried to enter my WP username and password but it doesn’t work.

Google Play and Apple Play Store Icon SVG Codes for Web Pages

The common way to display an image on a web page is showing image files by using <img src=”blabla.jpg”> tag.

But the problem is image files are not good enough if you scale up the web page, you will see the pixels.

Preventing multiple same ElectronJS apps to run at single time

Ciihuy SMTP Bulk Mail Sender

I’ve made a web application called Ciihuy SMTP Bulk Mail Sender for sending bulk/mass emails with a single click.

But I must say that:

  • We do not collect your input data on our server from this page. However if you have a bulk mail job, your data is stored temporarily on your web browser locally and deleted directly after your mailing job is done.
  • Some mailing servers has mailing limitation, for example you may only can send 200 emails per hour, not more. You must ask this to your service provider.
  • Some mailing servers lacks good mailing ability, just for example the email you send will go to spam folder of the recipient’s inbox.
