Hi by me -- It's really difficult for me to determine why certain scripts don't work simply by you explaining what you did. Nothing jumps right out at me. It would be much better if you could post the actual scene that does not work. That way I can test certain variables to determine WHY they fail. After I figure out why it doesn't work, either you or I can delete the scene so that you can post the working version of it.

MORE: I did notice one error in your "rectangles" script. You show: oncollide = (e)=>{scene.my.motor = true
scene.my.motorSpeed = 26}

You MUST have a semicolon after the word "true" which should separate the two commands. So, it should look like this: oncollide = (e)=>{scene.my.motor = true;
scene.my.motorSpeed = 26}

I don't know if that will fix your problem, but if it doesn't, then I will need to see the entire scene in order to troubleshoot it.

Thanks it works ..
But i forgot to tell you in the scene, those two rectangles in switch and motorfan zone it need {scene.my.polygon} script in collisionSet on script menu
To make the plug in power outlet zone can function as a breaker and connector,
But for some reason algodoo won't allow me to use {scene.my.polygon} script in collisionSet, and always Restoring to last known value
Did you know What is the problem

Sorry, I cannot go by your description. I need to see the actual script in order to troubleshoot it because you are probably leaving out some details that I would need to know. You cannot simply call a dentist on the phone and tell him you have a toothache and expect him to know exactly why. He would tell you to come in so he could examine it. Same thing here.

@Xray I already update this scene with adding the textbox hope you understand what i mean

Again, without me having the actual script to test I can only guess what might be happening. Obviously there's a problem with "scene.my.polygon". It might contain invalid data. For example, collideSet must be an integer value. It cannot be a bool (true/false) and it cannot be text ("This is text"). For collideSet, A=1, B=2, A and B = 3, etc. So, I suggest that you run your scene until it fails, then look at the data in scene.my.polygon to see what it is. You can do that simply by typing the variable by itself in that data entry area in the upper-left corner of any object. If it shows anything other than an integer, then you will need to figure out WHY the variable is getting stuffed with invalid data.

thanks Xray now everything its worked,
now i can peace

Great! I'm glad that I was able to help you.
