I want to use buttons to change object. when i press the Red button i want to show banana on market, blue button to show spider, yellow button to show robot and green buttons to show vase. -so sorry about my bad English-

Re: How to do this ?? (Virtualbuttons)

Start with the VirtualButtons sample. Take a look at the renderFrame method in VirtualButtons.cpp.

Thank you so much Kim. I will try to do.

Re: How to do this ?? (Virtualbuttons)

Kim I try it already.

Did you remove the teapot rendering code at the end of that function? If not, you'll end up rendering the teapot over your model, most likely hiding it. As always, make sure you're running ndk-build and refreshing (or cleaning) the Eclipse project after making changes to the native code. - Kim

thank you Kim. what the teapot rendering code that i must remove?:p

Re: How to do this ?? (Virtualbuttons)

It's very similar to the code you posted here.

Re: How to do this ?? (Virtualbuttons)

Thank you so much Kim:) I remove it already but teapot is disappear.

Did you define kSpiderScale? Make sure you do it before it is used in the file. We're getting into basic coding problems now. You'll need to conditionally render the teapot when buttons aren't pressed. - Kim

Re: How to do this ?? (Virtualbuttons)

I already define kSpiderScale. It not error right now but noting appear on my trackables. I know about c++ a little bit . Thus can you tell me how to write conditionally render the teapot when buttons aren't pressed or guide me a little bit. thank a lot:o

Re: How to do this ?? (Virtualbuttons)

Basic coding skills are a requirement for working with the SDK. Pick apart that renderFrame method until you understand it, then you should be able to work with it to conditionally render the model you want. You may also want to look at the FrameMarkers sample.
