Slopes steep.

[lukasz1985]

I'm trying to figure out what is the correct steep for slopes? And I can't find the solution.

The quesion is - what is the difference of height between level 0 and level 1 for example. I mean - if a tile is 1 unit long and 1 unit wide, what is the height difference? I've found value 0.41 pretty useful and I guess that is an outcome of the slope angle given in degrees - but still this is result of my guessing. Can anybody tell me the correct angles? Thanks!

At normal zoom, the difference between two height levels is 8 pixels.

http://newgrf-specs.tt-wiki.net/wiki/NM ... ile_slopes shows all slopes. If you want to render it, use the dimetric projection. The diagonals of the flat square tile is 64 pixels wide and 31 pixels high.

Thanks for that but could you specify a 3D angles and dimensions? The thing is I'm doing 32bpp stuff and I don't really care much about every pixel, yet counting that stuff.. I could figure out this but maybe you got the answer straight away. The things I need to know are explicitly displayed in the attached image.

I need to know:
- the angle
OR
- the height

You may want to check what zBase is doing. Since it uses rendering too, it should have values for your dimensions.

Otherwise, people drawing sprites manually don't think in your dimensions, they think in amount of available pixels for drawing,and the 2:1 ratio horizontal/vertical.

@Alberth Yeah, good idea

[lukasz1985]

Ok. So I've got the data form zBase, for anybody interested:
- Height is: 0,204155 units
- Angle is: 11,53856 degrees
