Button flipper
Step 1
Drag out a ||input:on button A click|| block to add code that runs when button A is pressed.
input.buttonA.onEvent(ButtonEvent.Click, function () {
})
Step 2
Grab an ||logic:if then else|| block and put it inside the ||input:on button A click||. We’ll use this, along with a random number, to decide if you’re going to win or lose.
input.buttonA.onEvent(ButtonEvent.Click, function () {
if (true) {
} else {
}
});
Step 3
Go over to LOGIC again and get a ||logic:0 < 0|| comparison block. Use it to replace the true condition in the ||logic:if then else|| block.
input.buttonA.onEvent(ButtonEvent.Click, function () {
if (0 < 0) {
} else {
}
})
Step 4
In the MATH toolbox drawer, pull out a ||math:pick random|| block and place it into the first slot of the ||logic:0 < 0|| block. In the second slot, type 5.
This picks a random number between 0 and 10. If the number is less than 5 it will run the code in the ||logic:if|| part of our ||logic:if then else|| block. But, if it’s 5 or greater, it will run the code in the ||logic:else|| part of our ||logic:if then else|| block.
input.buttonA.onEvent(ButtonEvent.Click, function () {
if (Math.randomRange(0, 10) < 5) {
} else {
}
})
Step 5
Drag the ||music:play sound|| and ||light:show animation|| blocks out to create the win and lose effects. You can pick the sounds and animations. Be creative!
input.buttonA.onEvent(ButtonEvent.Click, function () {
if (Math.randomRange(0, 10) < 5) {
music.powerUp.play()
light.showAnimation(light.sparkleAnimation, 2000)
} else {
music.wawawawaa.play()
light.showAnimation(light.runningLightsAnimation, 2000)
}
})
