drawing does not run on every tps

[jdemaria22]

Hi guys, i have a question about the Draw() function in ebitten.

sometimes the function Update() executing two or three times before de Draw() function.

For example, this is a sequence of my program with 165 TPS .

Update()
Update()
Update()
Draw()
Update()
Draw()
......

Someone can help me?

Sorry for my english

This is usual. For one frame (a vsync), multiple Updates can be called, or sometimes Update might not be called. Ebitengine tries to call Update the specified TPS times per second on average.

What about ebiten.SetTPS(ebiten.SyncWithFPS)?

In the first place, I'm not sure why you want to call Update exactly once every frame.

Update, find the information about the position of circles and images for draw, in 165 tps, the problem is that the elements that I draw flicker. And the TPS and FPS show me 165.

I don't quite understand what is going on. Could you show me your code?

[jdemaria22]

yes, of course

func main() {
NAME = strconv.Itoa(rand.Intn(RANDOM))
ebiten.SetWindowSize(screenWidth, screenHeight)
ebiten.SetWindowTitle(NAME)
ebiten.SetWindowResizingMode(ebiten.WindowResizingModeDisabled)
ebiten.SetTPS(ebiten.SyncWithFPS)
ebiten.SetScreenClearedEveryFrame(true)
ebiten.SetWindowDecorated(false)
ebiten.SetWindowFloating(true)
ebiten.SetVsyncEnabled(true)
game := &Game{}
option := ebiten.RunGameOptions{}
option.GraphicsLibrary = ebiten.GraphicsLibraryAuto
option.InitUnfocused = false
option.ScreenTransparent = true
option.SkipTaskbar = true
err := ebiten.RunGameWithOptions(game, &option)
if err != nil {
log.Fatal(err)
}
}

type Game struct {
}

func (g *Game) Update() error {
module.Update() //this update de information (values to draw)
return nil
}

func (g *Game) Draw(screen *ebiten.Image) {
scripts.DrawChamps(screen) // method to draw
ebitenutil.DebugPrint(screen, fmt.Sprintf("TPS: %0.2f\nFPS: %0.2f", ebiten.ActualTPS(), ebiten.ActualFPS()))
}

func (g *Game) Layout(outsideWidth, outsideHeight int) (int, int) {
return 1920, 1080
}

I can't tell why the 'flickering' happens from this code. I think there is an issue in the module or the script part.
