Function Syntax

void OnStationAttributeTrigger(char attributeName[]);

​
Description

This callback is called when the following three conditions are met:
  • Scenario attribute with the name specified in attributeName reaches the next attribute keypoint (value assignment) in the scenario timeline;
  • Scenario attribute property Trigger was set to true in the corresponding scenario file;
  • Scenario attribute with the name specified in attributeName belongs to the scenario station of a calling CAPL node.
This callback is intended to define a reaction on triggerable attributes of a scenario station assigned to the calling CAPL node only. If you want only react on a attribute triggering of all stations in the scenario, please use OnStationAttributeTriggerAll callback function instead.

Example

void OnStationAttributeTrigger(char attrName[])
{
  long stationHandle;
  char stationName[200];
  stationHandle = C2xGetStationHandle("%NODE_NAME%");
  if (stationHandle != 0 && C2xGetStationName(stationHandle, elCount(stationName), stationName) == 0)
  {
    // For all attributes of this station
    write("CAPL Node '%NODE_NAME%', Car2x/V2x station '%s', %f sec : OnStationAttributeTrigger called - Attribute '%s' = %f" ,
          stationName,
          TimeNowNS()/1e9 ,
          attrName,
          C2xGetStationAttributeDouble(attrName));

    // For concrete attribute of this station
    if (strncmp(attrName,"Speed",strlen(attrName)) == 0)
    {
      write("Car2x/V2x Station '%s', %f sec : OnStationAttributeTrigger called - Station Speed = %f",
            stationName,
            TimeNowNS()/1e9 ,
            C2xGetStationAttributeDouble("Speed"));
    }
  }
