Hello, I'm new

Okay so I was making my map, and I want to incorporate some of these fling type puzzles. Where you put a portal onto a slanted surface then jump through another and get catapulted across. The problem is my portals never appear on the angle, they wont connect just like when you shoot a non portal wall.

I have basically made a brush and then rotated it, not sure if I need to add any fancy brush entities to it.

Thanks

Is the face surface the correct size, IE is it large enough to accept a portal? Have you tied it to an entity or anything or is it still a world brush?

I've experienced problems sort of like this before. The issue I had was this:

I created a brush, converted it to a func_brush, then rotated it 45 degrees to angle it upwards. In game I could place portals on the surface but I couldn't pass through the portal at all. It was as if an invisible wall were blocking me.

If I converted the brush to a func_detail it worked fine at an angle. But I needed to rotate the brush as part of a puzzle so func_detail really wasn't going to work. Eventually I found that if I placed the func_brush straight up and down (not at an angle) then used a func_door_rotating to turn the brush at the start of the map, everything magically worked fine.

I suggest experimenting with func_details and func_brushes to see if anything fixes the problem.

I have a feeling its to do with the size, because I have tried to make the brush a func_detail and func_brush. Does any one know the dimensions for a portal?

that would be something like 128x64, or 256x128. It was something 2 to 1, anyway...

I thought it was 108x64

Could be, I can't remember... I once used pre-placed portals in a test map...

Ah, I suddenly remember: they weren't 2 to 1.

Dunno what they are, maybe you must look at the portal entity in Hammer.

108 x 64 is the size of the portal entity. I'll try using this entity to size up my flings.

Thanks for the help though!

I've had some func_brushes not allow me to pass thru, angled or flat. I've never had to have the brush rotated at the start of the map before. Hammer can't seem to make up its mind to allow or not allow.
