Hello,
I am currently working on a hover car, I am applying a force from the location of 4 objects on my cars to the ground, to get the location of the impact on the ground I use the trace line function. But when my car moves the lines are always in ■■■■■■ compared to the car, like if they could not follow the car.
Is it just visual ? If not, from where the problem could be from ?
I let you a link to a picture of my car hierarchy, of my line trace and a gif that show the problem.
according to the pictures you posted everything seems right and the video shows it working. i assume the lines your talking about are the debug lines. debug lines wont move with the actor so if your moving forward then they will appear behind you/
You can have a better view of the problem on the following gif: edit (better gif quality): Imgur: The magic of the Internet
So, is it just visual ?
pretty much. the lines are drawn and stick around for one frame. however they dont move with your car they stay in the play where they were spawned so the ones you see just before they disappear are from one frame ago. so since your car is moving forward every frame they will always appear behind you. if you really want to see all this in action switch your draw debug to persistent which will cause the lines to never disappear. the main thing is your blueprint functions properly right? if it works then your all set nothing to worry about.
