I didn’t
want to work on the game this week, for two different reasons. First reason
being I was sick. Wife went back to work found new germs and the house got
sick. So I spend Monday curled up on the couch binge watching Stranger Things
and eating hot soup. Second reason being I thought that implementing ducking
would be hard. Was I right? Kind of but not really.
I have
this fancy Ray Cast system set up for the player. Basically my player sends out
a Ray and the distance of the ray determines the player’s speed. So if the player is colliding with a box the
distance of the ray is zero and so the player’s speed is zero. But the hit box
I have representing the player is basically the player’s feet. So I needed to
double the player’s height and add the player’s head, ‘so to speak’. This
seemed really complicated to do. I knew how I thought this should work but
making it and thinking about it ARE two different things.
Well
turns out that I just needed to add the player’s height to the Y calculations up
for Ray Casts in the position Y direction. Negative remains the same. And then
increase the height of the X direction and suddenly we are Ray Casting with
everything covered! I do need to better look at this because it was some hack
code to accomplish this but it does work.
Then it
was just a matter of moving the player’s head to the position of the player’s
feet in the Y direction when user input is negative for Y. Setting this up
caused I bug that I haven’t quite figured out yet. Basically the bug goes
something like this: nine times out of ten ducking works as expected. Player
presses down and head.Y is equal to feet.Y. Then there is the one time when the
head.Y is -1 lower than feet.Y. So it creates a situation where you have
crouched SO low that your head has fallen through the ground. As a tester inconsistent bugs were slightly annoying
but as a dev they are the WORST. A game is made out of so many variables and
tracking down the one thing that one thing that broke everything is a pain in
the ass.
There
are other things not quite right with ducking at the moment, like you can move
left and right while ducking. So I have imperfect ducking at the end of the
week. I mean it was less of a head ache to set up than I thought and I have a
rudimentary version actually working, so overall I will call it a B-!
The
thing I set up earlier in the week before ducking was wind tunnels and
treadmills. Basically a vector that pushes the player in a direction when they
collide with this type of collision. This was something else that I thought
would be difficult and turned out to be REALLY easy. I slapped on some
classical music and in about an hour I had it working rather well. Then two
more hours and it was refined push collision. Maybe by the time next week rolls
around I will have refined ducking? Who knows.
I think
I am about ready to start arting this here game thing. Maybe slap some pretty
pictures on this and finally show off what it is supposed to look like! Oh I
guess I have to make those pictures. Going to close with a video of ducking and
push collision.
