the TDx_Library
the TDx9_Library
- Description
The Start() method downloads and plays an effect from the beginning, restarting the effect if neccessary.
The download only occurs when the effect has been modified or is not already present and the DIES_NODOWNLOAD flag is not set.
Exclusive level access to the acquired device is required.
Error values that can be generated are:
DIERR_INVALIDPARAM
DIERR_INCOMPLETEEFFECT
DIERR_NOTEXCLUSIVEACQUIRED
DIERR_NOTINITIALIZED
DIERR_UNSUPPORTED
- Parameters
Iterations
The Iterations parameter defines how many times the effect should be played.
This value can be set from 1 to INFINITE, but not all devices support multiple iterations.
If the effect has an envelope, it will be applied each time the effect is repeated.
To play an effect indefinitely without re-applying the envelope each time, change TDIEffect::Duration to INFINITE with TDx_InputEffect::SetParameters().
Flags
The Flags parameter defines flags indicating how the device should play the effect.
The described effect applies when the flag is set.
-
DIES_NODOWNLOAD
The effect should not be automatically downloaded to the device.
DIES_SOLO
Clear all other effects from the device before playing starting this one.
