(Unity2D) Increasing and Decreasing Stat Bar Issues - unity3d

Question

I have several stat bars, attached to objects, that shorten in length over time. If the PC collides with the object, the stat bar should steadily increase in length instead.
Instead, the bar lengthens to its fullest extent, and doesn't begin to shorten again until the PC interacts with another stat bar object; at which point the bar goes back to the length it had been previously.
This is the code for the progression of the bars:
void Update() {
if (contact) {
Increase();
Debug.Log("increasing");
} else if (contact == false) {
Decrease();
Debug.Log("decreasing");
}
}
void Decrease() {
if (filled > 0) {
filled -= 0.006f;
timerBar.fillAmount = filled / maxTime;
}
}
void Increase() {
if (filled < maxTime) {
timerBar.fillAmount = (filled += 0.006f);
}
}
In a separate script, I am keeping the conditions for the definitions of "contact".
void OnCollisionEnter2D(Collision2D collision) {
if (collision.gameObject.tag == "Player") {
barProg.contact = true;
Debug.Log("is touching");
}
}
void OnCollisionExit2D(Collision2D collision) {
if (collision.gameObject.tag == "Player") {
barProg.contact = false;
Debug.Log("is not touching");
}
}
Here are the images regarding the script attachments and colliders:
"yellowBar (progBar)" etc. are referring to the scripts attached to the canvas images of the statbars. So the little yellow depleting line (a statbar) is "yellowBar", and it references the script attached to the individual stat bar (progBar).
Shown below is an example of what I'm talking about. I refill the blue bar, at which point it stays the same until I go to refill the yellow bar, at which point the blue bar goes back to the amount it had been when I refilled it.

Answer 1

your going to want something like this, this is pseudo so bear with me....
bool healing=false;
public void OnTriggerEnter2D(Collisider2D col)
{
if(col.tag=="Player")
{
healing = true;
}
}
public void OnTriggerExit2D(Collisider2D col)
{
if(col.tag=="Player")
{
healing = false;
}
}
public void Update()
{
if(healing)
{
if(filled<maxTime)
{
timerBar.fillAmount += 0.006f;
}
}
}
bnwhose health your increasing, so each one needs the script.
you PC must be tagged "Player" to catch the collision.
your objects will need colliders, i assume they already have them.
and either the object or pc, will need a rigidbody. it seem you have most of this already. the reason this works is beacuae of the boolean. it sets it true when you enter the trigger and false when you leave it. so its only tru for that item while your touching that item, then inupdate while its true, we increase the healthbar.
putting this script on each of your objects directly will keep them from conflicting with each other, or updating the rong one.
good luck!

Answer 2

I have several suggestions to hopefully get you on the right track. This script should be attached the objects that fill up the status bars. you need to write a separate script to actually adjust the status bars based on the fillpercentage, but I'll leave that to you. This script is ONLY responsible for tracking how full, not displaying anything. This is good practice to separate your logic from your UI, since you can change one without affecting the other.
Also, you should avoid using "magic numbers" in your code. Make variables instead. see https://en.wikipedia.org/wiki/Magic_number_(programming)
Furthermore, you can switch between increasing and decreasing using a bool, rather than calls to separate methods. This keeps the logic in the same place and makes changing it in the future easier.
public class ColoredObject : Monobehaviour {
//bool to switch increasing and decreasing
bool increasing = false;
//can set this value in inspector to adjust speed it fills
//can even have different fill speeds for each color
public float fillSpeed;
//stores how full the bar is
float percentageFull = 100;
//if player contacts, start increasing
void OnCollisionEnter2D(Collision2D collision) {
if (collision.gameObject.tag == "Player") {
increasing = true;
}
}
//if player exits, start decreasing
void OnCollisionExit2D(Collision2D collision) {
if (collision.gameObject.tag == "Player") {
increasing = false;
}
}
void Update () {
UpdateFill()
}
public void UpdateFill() {
if (increasing) {
//fill based on time passed since last frame
percentageFull += fillSpeed * Time.deltatime;
}
else {
//empty based on time passed since last frame
percentageFull -= fillSpeed * Time.deltatime;
}
// keep it between 0 and 100%
percentageFull = Mathf.Clamp(percentageFull, 0f, 100f);
}
}
Let me know how it goes, and I can try to help you fine-tune it if this wasn't exactly what you wanted.
EDIT: if you want different increasing and decreasing speed just add another variable, and replace fillSpeed in the decreasing section.
