Tying a Slider to a Dialogue System Variable

[AlexNerd]

I'm trying to use the Dialogue system to make some turn-based combat, and I currently have the player health as a variable in the dialogue system. How do I make a health slider that adjusts with the health whenever the player takes damages?

Hi Alex,

Write a C# method, and register it as a Lua function. Something like:

Code: Select all

using PixelCrushers.DialogueSystem;
public UnityEngine.UI.Slider healthBar;
...
void Awake()
{
    Lua.RegisterFunction("SetHealth", this, SymbolExtensions.GetMethodInfo(() => SetHealth((double)0)));
}
public void SetHealth(double health)
{
    DialogueLua.SetVariable("PlayerHealth", health);
    healthBar.value = health;
}

Then use SetHealth() to change the health variable. Instead of setting the Script field to this:

Code: Select all

Variable["Health"] = Variable["Health"] + 10;

use this:

Code: Select all

SetHealth(Variable["Health"] + 10)

What should I attach the script to? The Dialogue Manager?

Hi,

Yes, that's a good choice.
