Canvas HP bar with gradients! version 2

[Hblade]

Version 2:

Hello everyone, this is version 2 of my gradient HP bar
New features from version 1:
Color change,
a gray bar that represents your max hp that hides behind your current HP
CONTROLES: use the arrow keys to add / minus HP
(screenshot)

Like the last version, no images are needed, so you dont have to worry about making tons of images for an hp bar
CONTROLES: Use the arrow keys to add / minus HP.

Here's the code for version 2:

Code: Select all

for (i2=0; i2<maxhp; i2++)
{
    setpen(69, 69, 69, 0, 3);
    moveto(i2, 0);
    lineto(i2, height-1);
    i2++;
}
for (i=0; i<hp; i++)
{
    for (gradl=0; hp>gradl; gradl++)
    {
    setpen(gradl, hp+gradl, 255, 0, 3);
    moveto(i, 0);
    lineto(i, height-1);
    i++;
    }
}


NOTE:
Your canvas can go all the way across the screen but it wont change the gray bar, You have to set the max hp and the normal hp in create actor. Look inside the GED file for more information

Old Version:
Hello, I made an H P bar that can be used for many games and it's not 1 solid color, it's a gradient and requires no images! It's all done by canvas.

Code: Select all

for (i=0; i<hp; i++)
{
    for (gradl=0; hp>gradl; gradl++)
    {
    setpen(gradl, hp, 255, 0, 3);
    moveto(i, 0);
    lineto(i, height-1);
    i++;
    }
}

Nice I think i could really use this and it looks cool , but how do i keep from going to far? Does it go on and on and on?

Version 2 fixes that. WHen your adding / subtracting the HP, instead of putting hp-=6 or something, you would put this:

Code: Select all

if (hp>0)
{
hp-=6;
}


And for adding HP via item or something you picked up,

Code: Select all

if (hp<maxhp)
{
hp+=50;
}


Where 50 is your item's recover rate or what ever

Then if you have like 45 / 50 HP, and you heal with 50 HP, to stop it from having 95 / 50 HP, make this code in the draw actor of your player

Code: Select all

if (hp>maxhp)
{
hp = maxhp;
}


The same with if you have 3 HP left, and someone does 40 damage, use this code:

Code: Select all

if (hp<0)
{
hp = 0;
}


But you wont even see it go pass 0
Theres also more advanced methods I could explain if you want me to.

Nice work, but since you have the erase being sent on the keydown (or player collision), why not send the draw then too? You can save a lot of cpu that way. Just remove canvas>draw actor alltogether.
