Sprite blinking effect when player hit
I have a player object and I have attached a sprite to it. I want to create the following effect:
When my player gets hit by an enemy, I want the sprite to blink for a short period of time, like in old arcade games (ex Sonic the Hedgehog).
How can I achieve this effect for my sprite?
Thanks in advance!
You need to add an animation on your player
In the animation window click Add Property and in the Sprite Renderer click on Enabled
Add a lot of your character frames in the animation and uncheck the box on the sprite renderer on every other frame
Make a script to have this animation play every time the player is hit
@parisk85 Here is the coding method if someone does not like the animation one :- (in this you will enable and disable the SpriteRenderer component at regular time intervals
create two timers :- (just copy paste them in your code :)) //Sprite blinking effect
public float spriteBlinkingTimer = 0.0f;
public float spriteBlinkingMiniDuration = 0.1f;
public float spriteBlinkingTotalTimer = 0.0f;
public float spriteBlinkingTotalDuration = 1.0f;
public bool startBlinking = false;
void Update()
{
if(startBlinking == true)
{
StartBlinkingEffect();
}
}
void OnTriggerEnter2D(Collider2D col)
{
if(something has entered :) ) //change according to your game
{
startBlinking = true;
}
}
private void SpriteBlinkingEffect()
{
spriteBlinkingTotalTimer += Time.deltaTime;
if(spriteBlinkingTotalTimer >= spriteBlinkingTotalDuration)
{
startBlinking = false;
spriteBlinkingTotalTimer = 0.0f;
this.gameObject.GetComponent<SpriteRenderer> ().enabled = true; // according to
//your sprite
return;
}
spriteBlinkingTimer += Time.deltaTime;
if(spriteBlinkingTimer >= spriteBlinkingMiniDuration)
{
spriteBlinkingTimer = 0.0f;
if (this.gameObject.GetComponent<SpriteRenderer> ().enabled == true) {
this.gameObject.GetComponent<SpriteRenderer> ().enabled = false; //make changes
} else {
this.gameObject.GetComponent<SpriteRenderer> ().enabled = true; //make changes
}
}
}
make changes where i mention and paste the rest of the code as it is, it will work :)
animation setbool is not work when collision enemy ?
Hey, Im quit late but maybe for people who will search in future, here:
private IEnumerator Blink() {
SpriteRenderer playerSprite = YourPlayerGameObject.GetComponent<SpriteRenderer>();
Color defaultColor = playerSprite.color;
playerSprite.color = new Color(1, 1, 1,1);
yield return new WaitForSeconds(0.05f);
playerSprite.color = defaultColor ;
}
when calling this function, make sure you do like so: StartCoroutine(Blink())
and if you wanna give this an arg and call it do it like so: StartCoroutine("Blink", arg)
If anyone still interested there is a small package that does exactly that :) https://assetstore.unity.com/packages/tools/particles-effects/damage-effect-23184
