Do you want to draw just the arc the ball follows or the complete half circle ?
i like to draw only one line rotating using 2 balls. i am trying using the block drawline but the drawline is drawing in every point in the rotating a new line getting a half life painting black like a half circle painted in black. no just one line display rotating. how can get only one line?
two balls because i like to get a line between two balls. no the half circle drawing, i will like get like gauge line
Draw me a picture of what you want.
You have deviated considerably from the original question...
i will like the black arrow. a line between two balls
I have got it this far (it completes the half circle)
Are you trying to make a gauge of some kind? If so, the approach is quite different, and why not say so in the first place, there are already many examples available.
ok thanks but its possible make that? using 2 balls and draw only one line? an animate a gauge using the line between the balls?. and where is there other examples?. please help.
Some of them:
but using 2 balls its not possible?. because i am trying to make a animation movement legs body using lines between balls like joints
Why a half circle ?
Why a gauge type approach?
Explain and show what you are trying to achieve...
Well, it is all here:
i know that i can make with javascript but i would like make using the app inventor canvas. its possible make that or no?. thanks
Yes, it is possible, you just need to translate the javascript to AppInventor blocks code (easier said than done, but should be possible)
ok thanks but only i need know what is the block can make a line between the balls but not draw only make the half circle follow movement. thanks for help
