Ive looked at the other posts have tried it, but it doesnt work. The other methods dont give me an error, but the 2 white triangles i should have are not there.
Error 1 The name 'ResourceUsage' does not exist in the current context
Error 2 The name 'ResourceManagementMode' does not exist in the current context
Error 3 The name 'ResourceUsage' does not exist in the current context
Error 4 The name 'ResourceManagementMode' does not exist in the current context
Pleas help! Thank you. :)

| | looks like you are missing a few things.
at the end of SetUpVertices()
vb.SetData<VertexPositionColor>(vertices);
|
at the end of SetUpIndices()
ib = new IndexBuffer(device, sizeof(short) * 6, BufferUsage.WriteOnly, IndexElementSize.SixteenBits);
ib.SetData<short>(indices);
|
Hope it helps.

| | | HI!!!! YOU! I know you maybe have 10. I know far weep 2 and crysis can't run you DX10 beacsue I reckon your record card is ancient. I guess your record card is 9.0c . Few record games must run on record games. | |
