What steps will reproduce the problem?
Run the example:
package main
import (
"fmt"
"log"
"github.com/hajimehoshi/ebiten/v2"
"github.com/hajimehoshi/ebiten/v2/ebitenutil"
"github.com/hajimehoshi/ebiten/v2/inpututil"
)
type Game struct{}
func NewGame() *Game {
return &Game{}
}
func (g *Game) Update() error {
just := inpututil.IsMouseButtonJustPressed(ebiten.MouseButtonLeft)
pressed := ebiten.IsMouseButtonPressed(ebiten.MouseButtonLeft)
if just {
log.Printf("just: %t, press: %t\n", just, pressed)
}
return nil
}
func (g *Game) Draw(screen *ebiten.Image) {
ebitenutil.DebugPrint(screen, fmt.Sprintf("FPS: %0.2f", ebiten.ActualFPS()))
}
func (g *Game) Layout(w, h int) (int, int) {
return w, h
}
func main() {
log.SetFlags(log.Ltime)
ebiten.SetWindowSize(480, 320)
ebiten.SetWindowResizingMode(ebiten.WindowResizingModeEnabled)
if err := ebiten.RunGame(NewGame()); err != nil {
panic(err)
}
}Run the input monitor with your device id (xinput without flags will list device ids):
#!/usr/bin/bash
xinput test-xi2 --root 12 | while read -r line; do
timestamp=$(date +%s%3N)
if [[ "$line" == *"RawButtonPress"* ]]; then
echo "[$timestamp] $line"
fi
if [[ "$line" == *"RawButtonRelease"* ]]; then
echo "[$timestamp] $line"
fi
doneWhat is the expected result?
Every times xinput fires, ebitengine example should fire a log too.
What happens instead?
The engine perceives frequent clicks (>2 cps) as single press:
ebitengine-real-fail.mp4
