2D 탄도 아크 너무 약함 Unity

Question

안녕하세요 다시 StackOverflow, 나는 현재 내 탄도 아크 코드로 고심하고있다. 내 문제는 아크가 너무 약해서 발사체가 거의 멀리 떨어져 바닥에 떨어지는 것을 의미합니다. 네가 나에게 줄 수있는 도움은 크게 감사 할 것이다.

void Awake(){ 
    spring = GetComponent<SpringJoint2D>(); 
    catapult = spring.connectedBody.transform; 
} 

// Use this for initialization

    LineRendererSetup();

Answer 1

:

private int actualFoce = 0; 

void Update(){ 
    Vector2 distanceFromCatapult = Vector2(transform.position.x - catapult.x, transform.position.y - catapult.y); 
    actualForce = distanceFromCatapult.magnitude + force; 

    //then the rest of your code 
} 

DisplayLine()에서 actualForce를 사용하고 발사체를 투사하십시오.
