When the ball touches the bat we will play a hit sound. To detect if the ball touches the bat we will use a touching color ? block and use the colour of the bat.
Add the following code to the Baseball sprite, underneath the change x by 10 block.
when green flag clicked
show
set size to (25) %
go to x (-210) y (45)
forever
change x by (10) // add new code under here
if < touching color (#ffc800) ? > then
end
end
Some of the sensing blocks allow you to set a colour to decide what they should do.
< touching color [#3e7144] ?>
< color [#ff6666] is touching [#4d86c1] ?>
You can choose which colour to use by clicking on the colour in the block and either using 'Color', 'Saturation' and 'Brightness' sliders to set the color.
Or you can use the eye dropper tool to choose a colour.
