how can I have a game object get a variable from a different object with collision
so i have a basic player and when the hit a pick up (health or damage) I want then to get the value or val variable off the object to pass into this function on there script
void OnCollisionEnter(Collision other) {
//if (other.gameObject.CompareTag ("Damage")) {
if (other.gameObject.name=="Damage"){
//GameObject timp= other.collider.gameObject.GetComponent (HP_Val);
HP_fill.fillAmount = HP.SetHP (**"How do I get Val here?"**);
HPtext.text = HP.desplay_HP;
//Destroy (other.gameObject);
if (HP.Helth == 0)
{
m_Animator.SetBool("KO", true);
}
}
}
I know this is do able but what am I missing?
lets assume that your damage/health pack classes are called "DamagePack" and "HealthPack" and each has a public variable called "value". Here is how you could test for and get those variables.
// Try to find components on the object.
HealthPack lHealthPack = other.gameObject.GetComponent<HealthPack>();
DamagePack = lDamagePack = other.gameObject.GetComponent<DamagePack>();
if (lHealthPack != null)
{
// you have a health pack just use lHealthPack.value to increase health.
}
if (lDamagePack != null)
{
// you have a damage pack just use lDamagePack.value to decrease health.
}
well that did help its not giving me an error wen i try to pass temp.Val into setHP
void OnCollisionEnter(Collision other) {
//if (other.gameObject.CompareTag ("Damage")) {
if (other.gameObject.name=="Damage"){
HP_Val temp= other.collider.gameObject.GetComponent (HP_Val);
//int x= temp
HP_fill.fillAmount = HP.SetHP (temp.Val);
HPtext.text = HP.desplay_HP;
//Destroy (other.gameObject);
if (HP.Helth == 0)
{
m_Animator.SetBool("$$anonymous$$O", true);
}
}
}
I do have a different error that is probably me just over looking something obvious
Assets/script/characterController.cs(99,57): error CS0118: HP_Val' is a type' but a `variable' was expected
This is because your type is (im assu$$anonymous$$g) HP_Val but when you're trying to use GetComponent you have to do it in certain ways. you can either use the type name as a string "HP_Val" as a System.Type "typeof(HP_Val)" or as a generic "GetComponent()" note the angle brackets in that last one.
https://docs.unity3d.com/ScriptReference/GameObject.GetComponent.html
The documentation of the GetComponent method should help clear this up and get you back on track.
