ググってみたけどこんな方法しかないような
wm geometry . 500x500
canvas .c -bg white
pack .c -expand 1 -fill both
.c create oval 230 230 270 270 -fill red
set moveto ""
bind . <KeyPress-Up> {set moveto "up"}
bind . <KeyPress-Down> {set moveto "down"}
bind . <KeyPress-Right> {set moveto "right"}
bind . <KeyPress-Left> {set moveto "left"}
bind . <KeyRelease> {set moveto ""}
proc move {} {
global moveto
switch $moveto {
up { .c move 1 0 -3 }
down { .c move 1 0 3 }
right { .c move 1 3 0 }
left { .c move 1 -3 0 }
}
after 10 move
}
after 10 move
方向を一つの変数でまとめてるけど方向別にすれば斜め移動も出来る
