How to change the mouse icon

[Thirsty Panther]

I'm working on a version of Operation Wolf www.arcade-museum.com/game_detail.php?game_id=8927 for the Halloween Games tournament.

In this the players character stays still and moves the mouse to target enemies. For this I need to change the default mouse pointer to a crosshair.

My current idea is to hide the default mouse pointer with window:hideMouse and to draw a crosshair image in its place. My problem is to getting the mouse co-ordinates and applying them to the crosshair image.

Window:GetMousePosition gives a vec3 but I'm clueless on how to apply these to the crosshair image.

Any help would be appreciated.

Window:GetMousePosition()

This function gets the mouse position. The X and Y components of the returned values are the screen coordinates, and the Z component is the mouse wheel position.

 

example:

window = Window:Create("crosshair",0,0,800,600,window.Titlebar+window.Center)

context = Context:Create(window)

world = World:Create()

camera = Camera:Create()

camera:Move(0,0,-3)

light = DirectionalLight:Create()

light:SetRotation(35,35,0)

 

model = Model:Box()

model:SetColor(1,.5,0,1)

 

crosshair = Texture:Load("Materials/Crosshair/crosshair.tex")

ch_width = crosshair:GetWidth()

ch_height = crosshair:GetHeight()

 

--window:HideMouse()

 

while window:KeyDown(Key.Escape)==false do

model:Turn(0,Time:GetSpeed(),0)

Time:Update()

world:Update()

world:Render()

 

m_pos = window:GetMousePosition()

 

context:SetBlendMode(Blend.Alpha)

context:DrawImage(crosshair, m_pos.x - (ch_width/2), m_pos.y - (ch_height/2))

context:DrawText("Mouse position: "..m_pos.x..", "..m_pos.y, 2, 2)

context:SetBlendMode(Blend.Solid)

 

context:Sync()

end

Hide the real mouse and make the mouse icon always the same position as the real mouse in an updating function should work. didnt go trough the code above

Thank you both.

 

The step I was missing was loading the GetMousePosition into a variable so that I could then get the X and Y co-ordinates from.

 

Thanks also for the factoring in the size of the crosshair. I probably would not have realized until much later that I had forgotten this as well.
