Bahh, dunno whats wrong - 02/20/11 23:09

Hey, I have recently been trying to make a simple 3rd person shooter in a simplistic style, everything was going swimmingly until I tried to make a health-bar script. I have pulled my hair out and just dont know what to do, normally i try to work things out myself before posting on any forum, but here is the script:

function healthbar(ENTITY* ent, var healthheight, var maxhealth)
{
VECTOR* temp;
while(1)
{
vec_set(temp, ent.x);
vec_to_screen(temp, camera);

PANEL* healthbar =
{
window(temp.x, temp.y, 20, 5, "windowhealth.png", ent.skill1 / maxhealth * 40, NULL);
flags = SHOW;
}

wait(1);
}

Thanks in advance.

I don't know what is wrong but I know an way to make a simple healthbar script for players; an variable, window panel + frame panel and a digit panel if you want that too. When you an action/function effects the player health just change healthplayer variable in that action/function.

e.g. what I use in one of my maps:

Code:

BMAP* healthbarframe_bmp = "healthbarframe.bmp";
... 
var healthplayer = 150;
...

PANEL* first_pan =
{
	pos_x = 1077;
	pos_y = 919;
	layer = 1;
	bmap = healthbarframe_bmp;
	flags = OVERLAY | SHOW;
}

PANEL* second_pan =
{
    window (1080, 919, 65, 25, "healthbar.bmp", healthplayer, 0);
    flags = SHOW;
}

PANEL* third_pan =
{
	digits (1100, 900, 3, "Arial#15b", 0.667, healthplayer); 
	flags = SHOW | OUTLINE;

If players regenerate health, you can add this code within a while loop in the main function;

Code:

if (healthplayer < 150)
healthplayer += 0.03;

Hope that helps somewhat!

o don't think that this code really helps him, because you have many errors!
so first think about your code and test it before posting!
corrected:

Code:

var healthplayer = 150;
...
PANEL* first_pan =
{
	pos_x = 1077;	//It works, but only for one screen resolution!
	pos_y = 919;	//The same here!
			//Fix: Function which updates the position
	bmap = "healthbarframe_bmp";	//Forgot quotation marks
	window (1080, 919, 65, 25, "healthbar.bmp", healthplayer, 0);
	//Can be used directly without new panel
	digits (1100, 900, 3, "Arial#15b", 0.667, healthplayer); 
	//Same here
	flags = SHOW;
	//Refresh isn't needed anymore
	layer = 1;
}

//Your snippet:
if (healthplayer < 150)
	healthplayer = minv(150,healthplayer + 0.03 * time_step);	//Timestep needed because of different frame rates!
