How to make and customize boss hp bar?

[Rakalborn]

Sorry, i am noob at luna, but i want to make hp bar for bowser in my project.

I have no idea. Just here because this had no posts and it would seem nobody cares. I care, but I don't know how. If somebody told you how, we could all learn how then it would be a nice Luna feature.

Please don't respond to help topics if you don't actually have an answer--it's a little pointless

[ThePieSkyHigh]

Sorry about that. It would really be nice though!

I would be able to help make it, but I need to know the following info:

• Graphics in .png format.
• Location in either X,Y of the setup, or the general area.
• Event to start the fight.

...but if I do it, I would need to suggest make the boss in question start with an event to trigger the showing of it.

[ThePieSkyHigh]

WAIT!

I had an idea!

If you make custom graphics, you should make the same amount as bowser's health depending on what your hitting him with. (e.g. 3 plants can kill him)

Later, make the graphics replace a BGO, and with an event make it disappear and make the next health bar appear. (the one with less life drawn in it!)

Idk if I explained well, I don't think I did. Maybe it could work with custom graphic for lakatu, that floats around and kinda follows you so the bar won't stay in one place like a BGO..

That's an extremely convoluted and inefficient way to do it. Drawing the bar with LunaLua is a substantially easier and more effective method.

[ThePieSkyHigh]

It's pretty simple if you ask me.

Added in 37 seconds:
without the lakatu, mind you.

[Hoeloe]

It's far, far simpler to just use Lua. Really it is.

[ThePieSkyHigh]

Oh. Well in that case can you script it?

Mechdragon already offered up his help in scripting it further up in this topic.

I think I should at least post some of my work (Quick Mach-up) to show a basis. (This is just a basic Health Bar using two graphics, and about 18 lines of code. I did not account for the death of Bowser in the code, but I am assuming this is similar to what you are asking for?

Looks really good!

Worth remembering that imagic exists and has a built-in function for drawing bars like that. Really this kind of health bar is ridiculously easy to make, only requiring 3 lines of code or so.

Although I should look into imagic a bit more than I already have, I can see my if-then statement on line 9 and 11 is not needed to just leave line 10, and the debug text on line 17 is also not needed. I also can replace the table "Bowser" with just "86" and also remove all spaces making it 6 lines less of code. I am sure the graphics would still be loaded with imagic and last time I looked into imagic, it takes around the same amount of code as glDraw. Then again, you are the expert here. (I also agree about Health being easy to display.)

You should be using ipairs instead of pairs too.

And drawing health the way you've done it is grossly inefficient. The imagic method uses the imagic.Bar function, which just does pretty much all of it for you. All you have to do is feed in a number between 0 and 1, and it'll draw the bar correctly. Yes you have to feed in images if you want textures, but if you just want flat colours then you don't.

This code in itself is really not good. Mix of global and properly-scoped variables, inconsistent variable naming, no reason to have 86 in a table (as you can just do NPC.get(id)). Also again definitely need to look into imagic. However you don't load images with imagic, just use imagic.Bar

Use this thing which we refuse to provide any documentation to in this topic!

imagic.bar{named arguments}

Available args:
x: x-coordinate
y: y-coordinate
width: width
height: height
percent: filled portion of bar (between 0 and 1, optional)
texture: the texture (optional)
align: alignment relative to pivot coordinate (default: ALIGN_TOPLEFT)
baralign: how the bar itself should be aligned, determines how the bar fills (default: ALIGN_BOTTOMLEFT)
bgwidth: width of the bar background (default: 2 pixels more than the bar itself)
bgheight: height of the bar background (default: 2 pixels more than the bar itself)
scene: whether you're drawing the bar to scene or screen coords (defaults to false)
color: color tint. if no texture is supplied, this defaults to green (else white)
bgtexture: texture for bar background (optional)
priority: render priority (optional)
outline: whether to draw an outline or not (defaults to false)
outlinecolor: color tint for outline, defaults to white

I was also unable to find documentation on the Wiki for lua. Thanks Enjl.

Apologies I keep forgetting imagic doesn't have documentation available outside its source file.
