Hi - I have an existing 1st person template project using the attached HUD blueprint setup (it reads an incoming heartrate from an Arduino sensor and displays it on screen) all works fine.
I copied the exact same HUD Blueprint into a new project which is a 3rd person template and none of the dynamic text displays - it only shows the words that are written in the text fields. I have changed the HUD in the project settings to use the HUD from this blueprint and I’ve also checked that the UE4DUINO plugin is activated for this project.
(I’ve tried this twic
e just in case I had accidentally adjusted the parameters in one of the 3rd person templates.)
Anyone have any ideas as to why the dynamic text shows in one and not in the other ?
The issue was that I had updated to windows 10 and I needed to update the UE4Duino plugin to the windows 10 version also.
Hello,
I was wonderding if you might have a solution for like an exact example of your HUD here just for a VR-environment in UE4.24?
I’m trying to include Arduino Data into a Widget Blueprint (Since I can’t do an HUD in VR, right?) it works in the Level Blueprint though and I can’t get it to work out in a Widget Blueprint.
Thank you very much in advance for your help!
Hi - its 4 years since I did this so I no longer have the project files but I have some development notes that might help:
I used a polar heart rate monitor connected to an arduino.
I used the ue4duino plugin and was able to bring the bpm into the main blueprint. I passed this bpm variable in realtime into a HUD created in the UI design component within unreal (I forget the name of the UI designer).
I tried several monitors with arduino but the polar was the most reliable but the user will need to be wirhin 2 metres of the arduino receiver.
Print screen can be used on the level blueprint but to DrawText you must use a HUD blueprint.
To ‘draw text’ with an imported font you must use a HUD blueprint - this HUD must be selected from the game preferences (I made a duplicate of the existing HUD with the crosshair in the first person template and altered this to my needs).
Arduino script created with 1.65 didn’t work with windows 10 - I updated it to v1.66 and it worked.
Best of luck
