Create the blood particles to splash blood upwards, set OneShot and Auto Destruct, and drag it to the Project panel to make it a prefab. If you are shooting the enemy with Raycast, instantiate the particles in the shooting script this way:

var bloodPrefab: GameObject; // drag the blood prefab here

... if (Physics.Raycast(ray, hit)){ // when you shoot... if (hit.transform.tag == "Enemy"){ // and hit an enemy... // find the necessary rotation... var rot = Quaternion.FromToRotation(Vector3.up, hit.normal); Instantiate(bloodPrefab, hit.point, rot); // and make the enemy bleed } } But if you are hitting the enemy with instantiated projectiles, add this code to the projectile script:

var bloodPrefab: GameObject; // drag the blood prefab here

function OnCollisionEnter(col: Collision){ if (col.transform.tag == "Enemy"){ var contact = col.contacts[0]; // get the first contact point info // find the necessary rotation... var rot = Quaternion.FromToRotation(Vector3.up, contact.normal); Instantiate(bloodPrefab, contact.point, rot); // and make the enemy bleed } Destroy(gameObject); // destroy the projectile }

so i would attach the projectile script to my bullet so when it hits the enemy it will play the particle?

Yes. If you are using a projectile to hit the enemy, attach the script above to the projectile prefab. When the projectile hits the enemy, it instantiates the blood particle at the contact point and destroy itself. You must set Auto Destruct and One Shot to true in the blood particle prefab, or else the blood will continue splashing in the same world point even after the enemy has moved to another place.

[Meta] is this question displaying "0" in the front page Answers counter for you guys as well? Looks like a QATO bug to me. O_O
