I want to position a health bar above each enemy using a for loop ...however when I run this I only see one health bar above one enemy..

not in loop:

+ Code Snippet

void make_enemy_healthbars()
{
	dbLoadImage("Media//Textures//green.jpg",22);
	for (int j=30;j<35;j++)
	{
dbMakeObjectPlane(j,12,2);
	dbTextureObject(j,22);
	}

}

in loop:

+ Code Snippet

for (int i=10;i<15;i++)  //enemys
{
		for (int j=30;j<35;j++)  //healthbars
	{
		
dbPositionObject(j,dbObjectPositionX(i),dbObjectPositionY(i)+40,dbObjectPositionZ(i));
dbPointObject(j,dbCameraPositionX(),dbCameraPositionY(),dbCameraPositionZ());


	}
}

you are positioning the whole 5 bars over one object everytime in the first for loop, so only the last once will take all the bars, if you want each one to take one bar make it like:

+ Code Snippet

for (int i=10;i<15;i++)  //enemys
{
dbPositionObject(i+20,dbObjectPositionX(i),dbObjectPositionY(i)+40,dbObjectPositionZ(i));
dbPointObject(i+20,dbCameraPositionX(),dbCameraPositionY(),dbCameraPositionZ());
}

NOTE: i ( eg. 11 ) + 20 = 31, so the healthbar with ID 31 is positioned over the object i ( 11 ).

i hope that helped.
