[C# XNA] Negative Scale?

[Chaosy]

Hi I got a image that I want to make smaller. The spritebatch.Draw(stuff) wont allow float values so I cant scale it to 0.2 or something. Solution?

How about the 4 seconds that it takes to do a google search? http://msdn.microsoft.com/en-us/library/ff433988.aspx

Use GIMP and resize the image to the size you want to use it at. If you want the size to be dynamic (not determinable before execution) then you may want to use a graphic plugin that supports float positions and scales.

Personally I think it does support scale by that nice scale parameter that GhostWolf so kindly showed us.

I did search ofc. Thanks for the link. However I dont know what to put in some fields.

spritebatch.Draw(button, new Vector2(20,400), null, null?, color.White, ???, ???, 0,2f, None, 0f)
//I think this is somewhat right, but as you see I dont know a few fields.

I tried this first. I edited with paint since there is a simple rescale function there. Sadly when I open with paint it removes the transperant background and replaces it with white background. I changed the chroma key to 255,255,255 but it still didnt remove it. Therefore I thought it would be easier to scale the image with code.

EDIT: I downloaded another editing program to fix it. Thanks anyway. rep +

EDIT 2: I could not rep you two more atm

Try

spritebatch.Draw(button, new Vector2(20,400), null, color.White, 0f, null, 0.2f, null, 0f)

You really should learn to read what they have written in the API. Remember the number of arguments have to match the number of arguments declared by the interface.

yeah my teacher showed me today. (I didnt know he would show it sorry for the trouble )

this is a working example if anyone cares about it.

spriteBatch.Draw(hp, new Vector2(0,400), null, Color.White, 0, new Vector2(0,0), 0,9f, SpriteEffects.None, 1)

0,9f is not a good idea to use. US compilers will interpret it as 2 parameters (as US/UK use '.' as their decimal delimiter unlike Germany and places which use ','). This will result in a compiler error as you are passing too many parameters to the function.

Basically the program has no way to distinguish between 0,9f being 0.9f (float constant) or 0 and 9f, 2 parameters of integer 0 and float 9.
