In the section below about coding the racing car, you’ll see why these different costumes are important. Duplicate it again to create the third sprite, and rotate it the other way. Right-click on the thumbnail of the sprite on the left-hand side, and select ‘duplicate’. It’s very easy to create these additional costumes. You’ve already done costume one, by creating the car facing straight ahead. It’s the exact same car, just rotated and saved as another costume. Once you’ve created your racing car, you’ll need to create three costumes for it – facing straight ahead, turning left, and turning right. If you’re making this game yourself and aren’t sure about your drawing skills, you can also upload your own images, so maybe look for a free stock photo that you like. In this case though, he couldn’t find the right thing, so decided to create one himself. Liam normally starts by looking through the Scratch library for a pre-made background that he likes. In a similar way to Liam’s volcanic eruption project, the background for this game is hand-drawn. Rubber band holding the wheel centred Setting the scene for the racing car game in Scratch The road background The benefit to the racing car game is that the steering wheel will always prefer to drive straight, keeping you in your lane. The second function of the rubber band is that it helps the steering wheel return to upright when it’s released. With the rubber band secured around the pulley wheel and the top of the frame, it keeps the shaft in place. Without it, the shaft would drop through the frame and get stuck. Where the shaft connects to the frame, the rubber band is a critical component. The steering wheel often lets go of the shaft Fortunately, it doesn’t affect the interaction between Lego Wedo and Scratch, so the race can just keep going. On a regular basis, the steering wheel detaches from the shaft, and Liam finds himself driving in mid-air. It fixes to a round 2×2 brick, which is a fairly small connection doing a lot of the heavy lifting. The connection of the steering wheel to the shaft is still a bit insecure. Liam is a fairly enthusiastic young driver, and hasn’t done any harm to the steering wheel yet.Ĭonnecting the steering wheel to the frame With the extra bracing, it works really well. You’ll see in the photos below that it’s been braced front and back in several places. Where the Technic bars and right angles are attached with pins, they were quite loose and the steering wheel didn’t hold its shape. Liam did his best to follow Mi 2 Tom’s build process, and it looked very similar, but something wasn’t right. Steering wheel base with Lego Wedo smarthub removedįor the steering wheel itself, there’s been a lot of substitution.Steering wheel base with Lego Wedo smarthub. When he’s ready to try the racing car game, he puts the smarthub in, connects the motor, and it’s ready to go. As a result, we need to be able to switch the smarthub between projects when he’s ready to test one.įor the modification of the base for the steering wheel, Liam built a structure out of Lego to hold the steering wheel frame, and left an empty space in the middle to slot the smarthub into. Right now, for example, there are three projects ‘mostly built’ and a fourth one in the planning stages. He tends to have several projects on the go at any one time. That will generally work really well, but Liam is a multi-tasker. The original base is built on top of the smarthub. It’s often quite a good thing, because he has to think outside the box to find solutions. Liam has the Wedo sensors, hub, motor, and most of the components, but not the full kit, so we needed some substitution. The steering wheel, as built by Mi 2 Tom, looks to be made from the Lego Wedo 2.0 kit.
