Trying to change cursor

[darekg11]

My sprite don't want to move, I managed to get Mouse X and Y coordinates, I also turned off normal cursor but I can't get Sprite to move at screen.
Code:

I bet it's kind of stupid error somewhere in code.
Thanks in advance.

don't know what language you are using exactly but as far as i can tell:

first of all you are hiding the mousecursor in the mainloop which is a waste of "performance" since you only need to disable it once.

second:
instead of checking for the mousemoveevent you can use the following

Code: [Select]


while( app.isopened() )
{
 // your event handling stuff

 // after the event handling
 CursorSpr.SetPosition( App.GetInput().GetMouseX(), App.GetInput().GetMouseY() );
}


third: use the setposition method of the sprite and not the move method. i think move is sthg else.

I am using C but with C++ compilator.
Could You explain more carefully?
So in loop:

while (sfRenderWindow_IsOpened(aaa))

I need to use:
sfInput_GetMouseX
sfInput_GetMouseY
sfSprite_SetPosition
And then before:
sfRenderWindow_Display
Use:
sfRenderWindow_DrawSprite
?

Code: [Select]


while(App.IsOpened())
{
    //GetTheInput...
   
    Sprite.SetPosition(MouseX,MouseY);
   
    App.Clear();
    App.Draw(Sprite);
    App.Display();
}

Yeah, I made stupid mistake before I forget to use GetInput function now everything works fine.
Thank You guys for reply.

Sorry for double post but I want to refresh topic, because I have question about cursor. Everything works fine but cursor looks like:


I want to hide that white background of cursor's image.
I thought that using fucntion sfImage_GetPixel to get background color and then use: sfImage_SetPixel to set color of necessary pixels to background color.

Is it a good idea?
Is there any simpler way to do this?

The function you need is sf::Image::CreateMaskFromColor().

[Quillraven]

imo use a .png format for the spritegraphic and make the background transparent. should be better (including performance) then hardcode this in your sourcecode.

[darekg11]

I used CreateMaskFromColor and it's almost perfect:

To do it perfect: Just use .png with a transparent background! Then you don't have to worry about it and even need some less codelines

Fixed, thanks.
