For this exercise, we will create a button that gradually turns a lamp on when pressed, then off again when unpressed.
...
Create a temporary push button (basic).
Use the button to gradually control a lamp object (advanced).
Making a Temporary Push Button
A temporary push button is a button that only emits a signal while pressed. When released, the signal turns off again.
...
Save the project and run the simulator. Pressing and releasing the button should change the Switch/Lamp state:
...
Changing a Value Gradually
Now, create another tag that will gradually change between 0 and 100:
...
| Code Block |
|---|
tag.write("isPressed", true);
var amountPressed = tag.read("amountPressed");
do {
amountPressed += 1;
if (amountPressed > 100) amountPressed = 100;
tag.write("amountPressed", amountPressed);
thread.msleep(10);
} while (tag.read("isPressed")); |
...
| Code Block |
|---|
tag.write("isPressed", false);
var amountPressed = tag.read("amountPressed");
do {
amountPressed -= 1;
if (amountPressed < 0) amountPressed = 0;
tag.write("amountPressed", amountPressed);
thread.msleep(10);
} while (!tag.read("isPressed") && amountPressed > 0); |
