Need Help with Raycast

[a548922]

I am needing to create a Raycast from a fixed camera location that can generate from the mouse location on the view port. Think of it like an Arcade game where you have to create a bullet that spawns from the camera to the location where the mouse is clicked.

This was my unsuccessful attempt:

Any Suggestions or Help?

Better use PlayerController - ConvertScreenToWorld. This will be MouseWorldLocation and line trace start.

Then use line trace end = MouseWorldLocation + CameraForwardVector*TraceDistance

Will this still use the Camera as the line trace start?

No, GetPlayerController → ConvertScreenToWorld already uses screen coordinates converted to world.

Its only going to one location on the screen… What am I doing wrong?

I’m sorry I am having trouble with this. Are you able to show me screen shot please?

Not screen location here. mouse location to world space for start

[redbox]

you already have ‘convert mouse location to world’ function in graph. just plug it into trace start.

This is what happens when I click anywhere on the screen:

Using:

Can’t ou see that you convert (0,0) screen location from that node?

Use mouse location also!
