I got an adventure game where there are cars driving on the road behind your house. I am trying to make the car randomly choose between directions when it comes to an intersection. I’m using a variable for directions and a math block that chooses a random number between the two directions you can move. The problem is that the car doesn’t change directions. It just goes straight forward. So it would be nice if someone could help  
Here’s the game

scene.onOverlapTile(SpriteKind.Player, assets.tile`"Tile of choice"`, function (sprite, location) {  
if (Math.percentChance(50)) {  
mySprite.vx = 0  
mySprite.vy = -100  
} else {  
mySprite.vx = 100  
mySprite.vy = 0  
}  
})

and “AI” is not a good word to use for this  
its more like “random Direction” no neural network needed
