Problems with DrawHp

[Ear1h]

While learning with Hud, I had a problem with the DrawHealthBar function

---

override void Draw(int state, double TicFrac)
{
Super.Draw (state, TicFrac);
fullscreenOffsets = true;
DrawHealthBar(CPlayer.health);
}

void DrawHealthBar(int hp)
{
int i = 0;
int draw_x = 20;
while(i < hp) {
DrawImage("HEART",(draw_x,-10));
draw_x += 10;
i++;
}
}

However, when I start it up, I get the following error:
"Can't play function DrawHealthBar from ui context"
"Can't call ui function DrawImage from play context (not readable)"

Show your whole statusbar code. It's hard to decide anything from these snippets.

Show your whole statusbar code. It's hard to decide anything from these snippets.

Here's all the code

Class MinecraftHUD: BaseStatusBar
{
override void Init()
{
super.Init();
SetSize(0,320,200);
}

override void Draw(int state, double TicFrac)
{
Super.Draw (state, TicFrac);
fullscreenOffsets = true;
DrawHealthBar(CPlayer.health);
}

virtual void DrawHealthBar(int hp)
{
int i = 0;
int draw_x = 20;
while(i < hp) {
DrawImage("HEART",(draw_x,-10));
draw_x += 10;
i++;
}
}
}

That error appears because you didn't specify a ZScript version.
To fix it, add this line to the beginning of your ZScript file: version "4.0", replacing 4.0 with your target GZDoom version.

Also if you aren't planning on making another class inheriting from your HUD and overriding your functions, you don't need to make DrawHealthBar a virtual function.

It's really working, thanks
