2d images PLEASE HELP!!!!

[only1skingle]

hey everyone,

I have looked at the tutorials but im lost within the code!

I am trying to make a 2d image appear on my program screen.

I am using the following code:

driver->draw2DRectangle(video::SColor(0,255,0,0),
core::rect<s32>(100,20,200,40));

but it doesn't seem to work.
any advice/guidance or a perfect code sample on how to put a rectangle in my program would be great.

Thanks

Are you calling this code inside your drawing loop?

[only1skingle]

yes

while(device->run() && driver)
{
if (device->isWindowActive())

And where inside your drawing loop are you calling this?

You also have full transparency enabled. Good chances that your rectangle is completely invisible, even if it's rendered.

no worries, i have now got a square placed in my window

i started messing around with the numbers in here:

core::rect<s32>(100,390,210,440));

however i am now confused as to what each number does.

As i thought maybe the (1,2 were x and y
and 3,4)); were size

but this doesn't seem to be the case.

so what do they do??

thanks

Position and position + size. Have a look at the constructor: irr::core::rect

So a box with width 100 and height 10 at postion 10,1 would be like

Code: Select all

irr::core::rect<irr::s32>(10, 1, 10 + 100, 1 + 10)
