maybe the health display sould be a bar or a dial or something graphic?
or is it just the position of it at the top of the screen like that which is putting me off?
Thanks for the suggestion. I've made one:
Anyway, I've found one problem when I doing the health bar. See below:
Initially, there was a 1-pixel-width artifact appearing on screen when the health bar was rendered. But I've checked everything: I selected that part in photoshop and pressed delete buttons several times to ensure nothing was there. Then, I also checked the size of the bar image, which is 256x32, fulfilled the 2^n size requirement. I don't know if this has something to do with Irrlicht or...
Anyway I've solved the problem by adding a rect clip to hide that 1-pixel-width artifact.
