This is a class that manages the properties of a currently playing sound effect. Objects of this class are generated for each audio clip played via the Audio.___Obj functions.
| PlayingSfxInstance class | |||
|---|---|---|---|
| Type | Function/Field | Return values/Value type | Description |
| function | PlayingSfxInstance:Pause() | nil | Pauses the object's sound or loop |
| function | PlayingSfxInstance:Resume() | nil | Resume the object's paused sound or loop |
| function | PlayingSfxInstance:Stop() | nil | Stops the object's sound or loop. always returns 0 |
| function | PlayingSfxInstance:Expire(int ticks) | nil | Change the timed stoppage of the object's sound |
| function | PlayingSfxInstance:FadeOut(int fade_ms) | nil | Fades out and stops the object's sound or loop with fade in length in milliseconds. |
| function | PlayingSfxInstance:IsPlaying() | boolean | Returns true if the object's sound is currently playing. |
| function | PlayingSfxInstance:IsPaused() | boolean | Returns true if the object's sound is currently paused. |
| function | PlayingSfxInstance:IsFading() | boolean | Returns true if the object's sound is currently fading in or out. |
| function | PlayingSfxInstance:Volume(int volume) | nil | Sets volume (from 0 to 128) of the object's sound. |
| function | PlayingSfxInstance:SetPanning(int left, int right) | nil | Panning stereo effects. This effect will only work on stereo audio. Meaning you called Mix_OpenAudio with 2 channels. The easiest way to do true panning is to call SetPanning(left, 254 - left); so that the total volume is correct, if you consider the maximum volume to be 127 per channel for center, or 254 max for left, this works, but about halves the effective volume. NOTE: Setting both left and right to 255 will undo the effect from the object. |
| function | PlayingSfxInstance:SetDistance(int distance) | nil | This effect simulates a simple attenuation of volume due to distance. The volume never quite reaches silence, even at max distance.
The volume never quite reaches silence, even at max distance. NOTE: Using a distance of 0 will undo the effect. |
| function | PlayingSfxInstance:Set3DPosition(int angle, int distance) | nil | This effect emulates a simple 3D audio effect. It's not all that realistic, but it can help improve some level of realism. By giving it the angle and distance from the camera's point of view, the effect pans and attenuates volumes. If you are looking for better positional audio, using OpenAL is suggested. NOTE: Using angle and distance of 0, will undo the effect |
| function | PlayingSfxInstance:ReverseStereo(int flip) | nil | Simple reverse stereo, swaps left and right channel sound. NOTE: Using a flip of 0 will undo the effect. |
