Unigine.Input Class
The Input class contains functions for simple manual handling of user inputs using a keyboard, a mouse or a game pad.
This class represents an engine's singleton.
Usage Example#
The following example shows a way to move and rotate a node by using the Input class:
Source code (C#)
void Update()
{
float move_speed = 1.0f;
float turn_speed = 5.0f;
if (Console.Activity)
return;
vec3 direction = node.GetWorldDirection(MathLib.AXIS.Y);
if (Input.IsKeyPressed(Input.KEY.UP) || Input.IsKeyPressed(Input.KEY.W))
{
node.WorldPosition += direction * move_speed * Engine.ifps;
}
if (Input.IsKeyPressed(Input.KEY.DOWN) || Input.IsKeyPressed(Input.KEY.S))
{
node.WorldPosition -= direction * move_speed * Engine.ifps;
}
if (Input.IsKeyPressed(Input.KEY.LEFT) || Input.IsKeyPressed(Input.KEY.A))
{
node.Rotate(0.0f, 0.0f, turn_speed * Engine.ifps);
}
if (Input.IsKeyPressed(Input.KEY.RIGHT) || Input.IsKeyPressed(Input.KEY.D))
{
node.Rotate(0.0f, 0.0f, -turn_speed * Engine.ifps);
}
}Input Class
