BASIC INFORMATION
GLOBAL CODE
- Code: Select all
void vBar (int barValue, int barMax, int barWidth, int border_R, int border_G, int border_B, int back_R, int back_G, int back_B, int fill_R, int fill_G, int fill_B)
{
int bar_i=0;
// Check valid bar values
if (barValue <0)
{
barValue=0; // if value negative set to 0
}
else
{
if (barValue>barMax)
{
barValue=barMax; // if value larger then barMax set to barMax
}
}
// Clear old display
erase(0,0,0,1);
// -------------------- Create Background ----------------------
setpen(back_R, back_G, back_B, 0.0, 1);
moveto(0, barMax+1);
for(bar_i = barMax+1; bar_i >0; bar_i--)
{
moveto(barWidth, bar_i);
lineto (0, bar_i );
}
// -------------------- Create Border ---------------------------
setpen(border_R, border_G, border_B, 0.0, 1);
moveto (0, 0);
lineto (barWidth, 0);
lineto (barWidth, barMax+1);
lineto (0, barMax+1);
lineto (0, 0);
// -------------------- Create Value Bar ------------------------------
setpen(fill_R, fill_G, fill_B, 0.0, 1);
moveto(1, barMax);
for(bar_i = 0; bar_i < barValue; bar_i++)
{
moveto (1, barMax-bar_i);
lineto (barWidth-1, barMax-bar_i);
}
}
POSITIONING BAR
For example, if playerShip is your player's ship actor & healthBar is the canvas actor containing your vBar, then:-
- Code: Select all
// THIS CODE WOULD GO IN YOUR CANVAS ACTOR'S CREATE EVENT.
// For this positioning to work as intended make sure you resize the canvas as close as possible to dimensions of your bar.
// Place bar CENTRED ABOVE player ship
x=playerShip.x + playerShip.width/2 - healthBar.width/2 - offSet; // you would enter offset manually to fine tune positioning
y=playerShip.y - playerShip.height/2 - healthBar.height/2 - offSet; // you would enter offset manually to fine tune positioning
// ALTERNATIVELY Place bar CENTRED BELOW player ship
x=playerShip.x + playerShip.width/2 - healthBar.width/2 - offSet; // you would enter offset manually to fine tune positioning
y=playerShip.y - playerShip.height/2 + healthBar.height/2 + offSet; // you would enter offset manually to fine tune positioning
// ALTERNATIVELY Place bar CENTRED LEFT of player ship
x=playerShip.x - playerShip.width/2 - healthBar.width/2;
y=playerShip.y + playerShip.height/2 - healthBar.height/2 - offSet; // you would enter offset manually to fine tune positioning
// ALTERNATIVELY Place bar CENTRED RIGHT of player ship
x=playerShip.x + playerShip.width/2 + healthBar.width/2;
y=playerShip.y + playerShip.height/2 - healthBar.height/2 + offSet; // you would enter offset manually to fine tune positioning
See my hBar post for information on how to get the bars working and change with your game.

Now onto next widget, arcBar ( a curved bar, looks much better on sides then vBars). This will keep me busy for awhile.
Goodnight all & happy Game-Editoring!
