cool and thanks.. um where can I get Raindrop.bmp

[Midnight]

try making one?

or search google but don't assume the material isn't copyright protected as always just cause it's available it doesn't mean free.

or you could search the lisence of the images... free image galleries are nice for that kinda stuff always check the lisence or request permission but the easiest way is to make it yourself.

[wowdevver24]

to make raindrop.bmp just open paint(ms or linux alternative) and set the size to 5px by 5px then select an appropriate color, I used dark blue, if you wish to modify this to be snow then obviously use grey #cccccc and make a 10x10 snowflake or series of snowflakes, also I'd suggest adding gravity, here is my code for irrlicht 1.6(obviously kudos go to the OP for their creation of the concept)

Code: Select all

now this does assume that you have a folder called media in either your debug or release folder and either irrlicht.dll in your system32 directory or your your executable directory, sorry to linux users on this part but as I'm quite sure I used DirectX as a renderer it was not as if you were not going to moan anyway, also aparently the setParticleSize is deprecated (ooh la de daa) but I'm going to use it anyway as it seems to work very nicely
