libnoise 是一个 Cpp 的噪声库 写了一个简易的教程 怎么把这个东西做成一个可以 iOS 用的 lib
libnoise from http://libnoise.sourceforge.net/
src, and select files like this:
No makefile, just .h and .cpp files, and don't select win32 folder, you are building in Xcode.
3.On your current Xcode project menu, Select
Frameworks & Library/
Cocoa Touch Static Library, hit next and name it "libnoise" or whatever :-)
4.Now, Drag files you selected in Finder to Xcode like this:
Things to remember to check:
- Copy items if needed
- Create Groups
- Add to targets, just select the new library we have created.
And now our project will looks like this: (I made a group from these files so you will see a top folder named libnoise)
5.Switch your target to libnoise (or whatever you named it when creating library target), we will check something.
Compile Sources, see if all .cpp files are in there.
7.Jump back the target to your app, make sure
Compile Sources have these:
- Xcode's target are on your app
- Target Dependencies have libnoise
- Link Binary With Libraries have libnoise.a
libc++.tbd in General Tab, or in Build Phases.
9.Create a UIViewController (like NoiseDebuggerViewController), and change
- #import "noise.h"
- paste these codes to viewDidLoad():
noise::module::Perlin myModule; double value = myModule.GetValue(1.25, 0.75, 0.5); NSLog(@"Value : %f",value);
and Press Run, make sure you have real iDevice plugged in instead of Simulator.
See the Log!
Value : 0.686347
Now you have libnoise on iOS! We are ready to use it for procedural planet generation on iOS!
