~GAME~ Use the left and right arrow keys, or the A and D keys, to move left and right. Use the W key, spacebar, or up arrow key to jump. ~DOCUMENTATION~ Drag the definition block into your backpack for future use. The custom block itself has 5 parameters, each of which are labelled with their respective default values. The parameters are listed as follows: ~s_x (1.0) Sets the speed along the x-axis. ~a_x (0.9) Sets the acceleration along the y-axis. This must be a number from 0 to 1 exclusive, and will round to the nearest valid tenth otherwise. ~wj <1> Sets whether wall-jumping is on. ~g (-1) Sets the force of gravity. This must be a negative number, and will become negative if positive, or default back to -1 if 0. ~h_j (15) Sets jump height. This must be a positive number, and will default back to 15 if negative.
Credit to @djpro again for the base again. (I'll maybe try to stop doing so much stuff with it for the time being) Please remix this, even if it's just to test different values out!
