Note

In the previous code, to check for the sign of hsp, we used the sign function .

sign(num) is a function that given a number num returns 1 if num is greater than 0, -1 if it’s less than zero, and 0 if it’s equal to 0.

Now open up room0 and add two instances of obj_block_brown or obj_block_red to the left and right side of obj_player instance. Running the game, you can verify that obj_player will collide with the blocks being unable to pass over them (Figure 8-5).

Figure 8-5Now we can block Berry using children of obj_block (in this case obj_block_brown)
