So I followed [Reuben Ward’s Tutorial on making a whiteboard][1], but instead of using a FPS, I used a sphere which is always at mouse location. So far so good… NOT! Because whenever I use it, there is only a circle in the middle of the whiteboard and I have absolutely no idea what I’m doing wrong! Here are some screenshots:
BP_Sphere:
BP_Whiteboard:
And this is how it looks:
Thanks for any help in advance!
Right after event ‘Draw on WB’ you multiply by scalar ‘0.0000’. If you breakpoint ‘Set Vector Paramateter’ you’ll probably see it is always a zeroed vector. I haven’t seen the tutorial, so I’m not sure what is actually supposed to go there.
Unfortunatley, that didn’t help… but still, thanks for your answer!
PrintString the ‘Location To Draw’ pin on ‘Draw on WB’ event. What does it return?
Also, Is ‘UV from hit result’ checked in Physics? The UV Collision node tooltip says you have to.
Now I’m really confused… PrintString gives coordinates between 0 and 1, and yes, ‘UV from hit result’ is activated… Maybe it’s the board itself? I used a cube
I think you may be missing a parameter name in BP_Whiteboard: when you set the Vector Parameter Value in the Marker Material Instance the parameter name is set to None, but probably should be set to DrawLocation or something like that.
That… actually worked! And makes sense… Thanks PabloNajurieta, and also salm for your help! One last question: Do you think it’s possible to draw a texture?
I was confusing the Vector2d to Vector conversion node with a multiplication node. They both are marked with ‘*’, I think.
Anyway, nice catch, PabloNajurieta.
