changeing the img
You need to know the previous health, and you of course need to know the new health. If your new healt is less than the previous health, you can use the setImage() action to change the image. Between the () you put the name of your picture, which is stored in the pictures folder of your project, between "" like:
1 | setImage("myImage.png"); |
that bit i understand
but how would you find the previus health and the new health health??
Create an instance variable for your previous healt:
If you have a method which sets the health - a parameter, add this line at the beginning of that method:
Also add another method:
Call this method from the method which sets the health - a parameter:
Succes!
1 | private int previousHealth; |
1 | previousHealth = yourVariableWhichHoldsTheCurrentHealth; |
1 2 3 4 5 6 | private void lookForHealthDifference(){if (previousHealth > yourVariableWhichHoldsTheCurrentHealth) { setImage("myImage.png");}} |
1 | lookForHealthDifference(); |
No, just an instance variable:
This must be stored in the class which shows the health, because it MUST know what to display!
1 | private int yourVariableWhichHoldsTheCurrentHealth |
that's also possible, is just said yourVariableWhichHoldsTheCurrentHealth because that would be easier to understand for you as you would read it here, but I didn't meant you must use it in your project.
ok im really confused im useing danpost's health bar and i cant find health value but i just had idear :D
You maybe have to redo your code of the health bar, and start off by using a variable which you convert into a health bar. That's what I do sometimes when I realize I did something wrong.
