I'm new to netlogo and i'm trying to make a slider that allows you to change the size of the turtles. so far i've made a slider called size-of-turtle and in the code i tried putting: "set size size-of-turtle" but i just get an error message. please help.
Best How To :
So you've made a slider with a global variable size-of-turtle. Do you have a procedure that will actually tell the turtles to do what you ask?
And yes, please show your error message. If you have a slider that nothing refers to, nothing will happen when you change the values on the slider. I suggest creating a turtle and running the code
ask turtles [set size sizeofturtle]
somewhere, preferably in a forever loop so that it is easy to see the change as you move the slider.
