3-8 Flying Fish and Reeling it In

To start on some cleanup this week, I wanted to address the fish floating to the bobber. In my research, I found out about the split struct pin option when you right-click on certain options in blueprints. In this case, splitting it was able to split the locations in the level script into the X Y, and Z coordinates. 

 

Initially, I tried plugging in the X and Z values as normally Y is the vertical axis (the axis I do not want to track) but in Unreal, Z is the vertical axis so as shown below, attaching the X and Y stops the fish from tracking vertically. 


The next was a plan to try and get a placeholder catch in, and to do this I wanted to use one of the existing mappings to "pull" the fish in. After looking it up and seeing the project Input settings were the place to start mapping the button, I had to dig through the VR Template to find a button I could use. I initially planned on using one of the triggers, but I remembered that triggers were used to grab objects, So I settled on one of the face buttons for now. Looking in there is where I found the name that I will need to call later. 



The Next step in pulling the fish in is making sure the fish is actually on the line. which by adding a variable on the left, named "Hooked" I can set it to true during the existing collision detection. 




The last step before loading up the game and trying to catch a fish was to actually look for the button press, and the new variable. In my research and something I actually tried to make the fish return, a certain node came up, the Branch node. From my understanding, this functions like an If statement, checking for a condition and then continuing the node flow. Linking one of these up to the "IA_Menu_Toggle_Right" and the "Hooked" variable should allow the nodes after to only happen when both are happening, in this case, it is just going to delete the fish. 


And the result? 





Turns out there's an actual menu that the button opens up, and that input overrides the catching of the fish. 

To fix this, I made a very quick input action and mapping based on the other ones in the template, and mapped it to A on the touch controller:




This however, also did not trigger the catching. After messing with it a bit more, I went to test it and.... my Quest died. Turns out it was on when it wasn't plugged in so I can't test that, but the point of the temporary catch was more to get the logic in place for the option tracking to come in the next two weeks.

3-16 Speed Measuring

Image
 So, reeling the fish in. Lots of good feedback here last class and I'm going to go over how I think this would best be achieved based on what I heard. The plan is to look at the speed of the player's hand to determine if they are "reeling" in the fish, and that same measurement could be taken from the rod to see if the rod was yanked back. Basically measuring the speed of the objects in some capacity is how this fish is going to get pulled in. Pretty conveniently, there is a velocity module in UE5: https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/Transformation/GetVelocity/ Getting into the blueprints now, this is what I decided to try first  On paper, Looking at the right controller in the VR pawn, it should shoot out how fast the right controller is moving. After adding ab it of logic in there, the blueprint now looks like this: I made a new float there as the threshold and measured the Y and Z velocity based on how the player loads into the game. It...

2-28 Fishing Line and Crashing Research

 So, with the very rudimentary fishing system in place, it was time to start moving forward with getting the next mechanic in place.  First, I started with a look at why my UE5 keeps crashing.  This resource from Epic themselves has a few possible solutions to the error that comes up: https://docs.unrealengine.com/5.0/en-US/how-to-fix-a-gpu-driver-crash-when-using-unreal-engine/ In addition, here's a video I found that does look that those solutions in action: https://youtu.be/Vejhv9QmNGM After spending time getting those things in order it was time to look into the fishing line itself, starting with looking at how other people have done something similar.  The closest example I could find was this Reddit thread: https://www.reddit.com/r/unrealengine/comments/s0aw03/i_made_a_toy_fishing_rod_using_cable_components/ He achieves the look of the rod with 3 cable components, and it's only really the one on the end that changes length. This might be the easier of the ...

2/9 Pt.1 - Disaster

  So far for production today, things have been going awful.  Mainly, my main drive is only 128gb, which has given me way more trouble than it should be. It has held me back from updating Steam Vr, it throws up 2-3 errors per time I open Unreal, but I'm pushing through it.  I've fought through it all to get a small scene together after hours of trying to get everything working. The number of hours just watching shaders compile and trying to get through all the Facebook walls just to use my quest after not turning it on in a while is insane but I managed to be sort of where I wanted to be.  A lot of the struggle this week was getting the pipeline for the new project in place, and now with all that set up and figured out, full production should go alright.
