In-Depth Information
Now, create a new object and name it
obj_Enemy
. Link the new sprite to it; then, add a
create event and drag in a code block.
There are three essential variables we need to create for this object: one to control the
speed, another to control the direction it moves in, and one more to control its up/down or
left/right state. Let's name them
spd
,
dir
, and
dir2
. We are going to use the choose
function on the
dir
variable and the
dir2
variable. The choose function will randomly
pick between a set of 16 or less arguments that we enter. In this case, for the
dir
variable,
we will enter two arguments;
0
and
1
.
0
will mean horizontal movement and
1
will mean
vertical movement. For the
dir2
variable, we will enter
-1
and
1
for left and right, re-
spectively. For the speed variable, we will use the
random_range
function again and
put in a range of
1
to
8
.
Here is our create event code:
