CreateSprite

[Pleca]

Has syntax for CreateSprite function changed? The following line of Lua code produces an error, even though it worked perfectly fine yesterday.

local statsSprite = CreateSprite(world, font, "", fontsize)

Make sure that font is not NULL.

Yeah, you're right font isn't loaded, so it's NULL. However, I created a new project and tried running the example from the docs, and I got the same result.

-- Get the displays
local displays = GetDisplays()

-- Create a window
local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_TITLEBAR + WINDOW_CENTER)

-- Create a framebuffer
local framebuffer = CreateFramebuffer(window)

-- Create a world
local world = CreateWorld()

-- Create a camera
local camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC)
camera:SetClearColor(0.125)
camera:SetPosition(framebuffer.size.x * 0.5, framebuffer.size.y * 0.5, 0)

-- Create sprite
local fontsize = 36
local font = LoadFont("Fonts/arial.ttf")
local sprite = CreateSprite(world, font, "Hello, World!", fontsize)
local rect = CreateSprite(world, font:GetTextWidth("Hello, World!", fontsize), font:GetHeight(fontsize), true)

--sprite:SetPosition(0,0,0)
rect:SetPosition((framebuffer.size.x - rect.size.x) * 0.5, (framebuffer.size.y - rect.size.y) * 0.5, 0)
sprite:SetPosition((framebuffer.size.x - rect.size.x) * 0.5, (framebuffer.size.y - rect.size.y) * 0.5, 0)

-- Main loop
while (not window:Closed()) and (not window:KeyHit(KEY_ESCAPE)) do
    -- Update world
    world:Update()

    -- Render world
    world:Render(framebuffer, true)
end

Not sure what I'm doing wrong, but I keep getting these errors:

 

Loading font "Fonts/arial.ttf"

Error: Failed to load font.

Error: Failed to load font "Fonts/arial.ttf"

Deleting font "Fonts/arial.ttf"

 

I'm sure arial.ttf is present in the Fonts directory.

Here is a simple font test project using the example from the docs. There's a possibility I'm doing something wrong, but I really don't know what.

Stay tuned, I know the cause of this...

[Josh]

Okay, it should work with the update I just uploaded. You need to update your project to get the latest binaries.

Thank you Josh, it's working now.
