dxDrawImageSection - problem

[stefutz101]

Hi . I'm trying to make a new health bar, but i'm got stuck.

I'm trying to do it with relative positions, because i've tried with absolute position and at some resolution it works bad.

Photo is 485 x 425 px.

Maxim health is 12000. I can do it , but i don't know why it looks like this :

https://s32.postimg.org/krx2y33ad/mta_s ... _11_13.png

i'm trying to draw 200 px from that photo so :

my resolution is 1366*768

200/1366 = 0.1464

dxDrawImageSection(screenW * 0.6340, screenH * 0.0130, screenW *[ 0.1464], screenH * 0.5534, 0, 0, 425, 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false) 

And it looks like this:

https://s32.postimg.org/krx2y33ad/mta_s ... _11_13.png

full photo (485px)

485px/1366 = 0.3551

dxDrawImageSection(screenW * 0.6340, screenH * 0.0130, screenW *  [0.3551], screenH * 0.5534, 0, 0, 425, 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false) 

And it looks like this:

PS: i used "[,]" to make that number more visible.

Any help ? Please ?

You're modifying the width of the image but not the width of the section you're taking from the image.

[stefutz101]

Ok , and how i can fix that ?

Can someone give me an example how i must draw 200 px from that image ?

[stefutz101]

Help , please ?

Try this:

dxDrawImageSection(screenW * 0.6340, screenH * 0.0130, screenW *  0.3551, screenH * 0.5534, 0, 0, (getElementHealth(localPlayer)*425)/100, 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false)

You're not using it right, you're changing the width which is wrong. What you want to change is the parameter called usize.

Since you always have it at 425, it will draw the entire image. And since you're changing the overall width instead of the section length - it gets squeezed like the picture you showed.

Yah it works but it don't works like i want .

Why the image is moving in right once my health is decreasesing ?

Any help ? This was my real problem , i don't know how to fix that , first time i think i was doing something wrong , but why the image leave that border ?

Show us how you modified the code.

[stefutz101]

Show us how you modified the code.

dxDrawImageSection(screenW * 0.6340, screenH * 0.0130, screenW *  0.3551, screenH * 0.5534, 0, 0, ((getElementData(getLocalPlayer(),"blood") or 0)*425)/12000, 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false) 

My maximum health is 12000 . So if i will have maximum blood it will be 12000 * 425 / 12000 = 425. When i have 12k blood it is displayed fine . (see photos)

[stefutz101]

So anyone know where the mistake came from ?

[Dealman]

Sorry for the delay, not as active on these forums anymore. Try this;

dxDrawImageSection(screenW*0.6340, screenH*0.0130, screenW*0.3551, screenH*0.5534, 0, 0, (((getElementData(getLocalPlayer(),"blood") or 0)/12000)*425), 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false)

I fixed it . Not this was problem . But thanks anyway

Now i have another question :

Why at 3000 blood , it looks like 0 blood , i mean that health bar is empty . Why it is imprecise ?

Did you try what I posted above? Your issue was the math being incorrect, sounds like it still is.

[stefutz101]

Same problem .

I can't fix it fuck off.

Look , the code :

local x = (((getElementData(getLocalPlayer(),"blood") or 0)/12000)*485)/screenW 
    dxDrawImageSection(screenW * 0.6340, screenH * 0.0130, screenW *  x  , screenH * 0.5534, 0, 0,((getElementData(getLocalPlayer(),"blood") or 0)/12000)*425, 425, ":DayZ/images/health.png", 0, 0, 0, tocolor(r, g, b, 170), false) 
     

Image have resolution : 425x425 px.

But i want draw it at 485x425 px.

2 Problems :

1)

my resolution : (1366x768x32)

https://s31.postimg.org/6ujkt0rq3/mta_s ... _35_54.png

my friend resolution (1280x1024x32)

https://s32.postimg.org/8lht9awz9/mta_s ... _05_05.png

2)

at 3000 blood health bar is still empty .

I don't know how to fix this thing , i don't know why it works at me , but my friend have that visual bug ... .

PS :

getElementData(getLocalPlayer(),"blood") = 3000

(3000/12000)*485 = 121.25

(3000 * 485)/12000 = 121.25

It is the same thing , not this is the problem ...

[Dealman]

You're changing the width as well, don't do that. Only usize.
