Easy Gravity and Good Healthbars

I went on the GMC and found a list of a bunch of awesome codes that work wonders.
Here's a code for Easy yet Good Gravity for Platformers:

1. Easy gravity (platformers)

Code:

if !instance_place(x,y+1,obj_Solid)
gravity=0.5
if instance_place(x,y+1,obj_Solid)
gravity=0
if vspeed>10
vspeed=10


This code helps because it creates gravity ONLY if there is space under you that doesn't have a solid object. It also limits your vertical speed which helps with falling through floor bugs. Lowering the number helps more but may make it look less realistic. Try using different limit amounts. Change obj_Solid to whatever object you use for your ground. It can be a parent object if you use more then 1 for your ground objects.


And here's some awesome code for a Good Healthbar.

Good Healthbar

Code:

//DRAW:
draw_set_color(c_red)
draw_line(x,y-10,x+linelength,y-10)
if hpamount > hpmax hpamount = hpmax
if hpamount < 0 hpamount = 0

//STEP:
linelength= hpamount / hpmax * sprite_width


I've been asked many time on how to make a healthbar and many times the person wants it to only be so long even if it's a lot of HP. (just goes down slower...etc) Well this code does it all. This one uses a line which is smaller and cleaner looking rather then a rectangle. Just set hpamount, hpmax, and make sure linelength=0 is in create. Also be sure to put the first part of the code in draw and the second part in step. You can mess with the numbers like the 10s for the height (raise number to raise bar). Now you can set any objects health and not worry about line lengths!

thanks for moving it.

I've got an easier healthbar code that works for individual objects.

Code:

draw_healthbar(self.x,self.y-4,self.x+31,self.y,hp*10,c_red,c_lime,c_lime,0,true,true)

Make a hp variable in the create event, in this code the default hp is 10, so it says hp*10 so it's 100. Change this. If you have a hp of 100 get rid of the *10, if you have a hp of 50 make it *2 etc, so it's 100.

cool!

Yeah, the health bar code I posted was for the Player's Health bar. But there both awesome.

After so long, I try and try to get individual healthbars to work, and I find out you can do it with one line of code. I was both annoyed and glad.

Ive never needed healthbars, although i may use this. Any codes for 3d health bars?

Would it not be the same?

you should try doing that in 3d

I can type everything I know about 3d in one post.

Code:

d3d_start()
d3d_end()

How will I know how to make healthbars in 3d?

do you mean like a 3d box for the health bar 3d

wouldn't you just use the code

Code:

{
  d3d_set_projection_ortho(0,0,640,480,0);
  d3d_set_hidden(false);
  draw_healthbar(x1,y1,x2,y2,health,c_black,c_red,c_lime,0,true,true);
  d3d_set_hidden(true);

}

???

Is it possible to create two separate health bars for two different objects at the top of the screen, you know like street fighter?

By the way Elmzran, I tried using the codes for the health bar and it did work to some degree, it's just the actual sprite for the object disappears.
I know it may have something to do with the DRAW event but I just don't know what!

Actually no it's ok, I managed to figure it out for myself.
Try my new game to see for yourself.

If an objct has a draw event it won't draw itself, you have to tell it to.

So in otherwords, in the create event the first action should be to draw the sprite of the object....right?
(I suck at code)

go away i am back

Oh my god puppy's back!
