* @page tutorial_ephysics_slider EPhysics - Slider
|
||||
*
|
||||
* The purpose of this example is to demonstrate the EPhysics Slider
|
||||
* usage - The code applies slider on three cubes.
|
||||
*
|
||||
* For this example we'll have an EPhysics_World, and four basic
|
||||
* EPhysics_Bodys.
|
||||
*
|
||||
* The basic concepts like - defining an EPhysics_World, render geometry,
|
||||
* physics limiting boundaries, add an EPhysics_Body, associate it to evas
|
||||
* objects, change restitution, friction and impulse properties, were
|
||||
* already covered in
|
||||
* @ref tutorial_ephysics_bouncing_ball
|
||||
*
|
||||
* You can use also a P2P (point to point) constraint:
|
||||
* @ref tutorial_ephysics_constraint
|
||||
*
|
||||
* @section add-slider Adding a Slider
|
||||
* @dontinclude test_slider.c
|
||||
*
|
||||
* Slider is a constraint that will limit the linear and angular moving of
|
||||
* a body.
|
||||
*
|
||||
* We'll add three sliders on the cubes, starting with the highest purple.
|
||||
*
|
||||
* First we need to create a specific variable type to get EPhysics_Body
|
||||
* constraint and create a new slider constraint passing the body which we
|
||||
* want as parameter.
|
||||
*
|
||||
* @skipline EPhysics_Constraint *constr
|
||||
*
|
||||
* @skipline constraint = ephysics_constraint_slider_add(box_body2
|
||||
*
|
||||
* Here we define the linear moving limits of the slider constraint, in this
|
||||
* case we just set moving limit down on Y axis (under), but if we wanted we
|
||||
* could set left, right and above also.
|
||||
*
|
||||
* @skip ephysics_constraint_slider_linear_limit_set(constraint, 0,
|
||||
* @until , 0, 0);
|
||||
*
|
||||
* Here we set the angular moving limits of the slider constraint. The angular
|
||||
* moving limits is defined in degrees and will limit the moving on Z axis, in
|
||||
* this case we just set the clockwise direction, but if we wanted we could
|
||||
* set the counter clockwise direction also.
|
||||
*
|
||||
*
|
||||
* @skipline ephysics_constraint_slider_angular_limit_set(constraint, 0, 45
|
||||
*
|
||||
* When this cube falls by the gravity, the slider constraint will act limiting
|
||||
* its linear and angular movings, giving the impression that its hanging.
|
||||
*
|
||||
* For the next two cubes is the same process.
|
||||
*
|
||||
* Now we set the slider constraint of the highest blue and lowest purple,
|
||||
* limiting moving limits to the left on X axis and applying an impulse
|
||||
* to the left where the two cubes will be limited by the slider constraint
|
||||
* and pushed back.
|
||||
*
|
||||
* @skip constraint = ephysics_constraint_slider_add(box_body3
|
||||
* @until box_body3, -240, 0);
|
||||
*
|
||||
* @skip constraint = ephysics_constraint_slider_add(box_body4
|
||||
* @until box_body4, -600, 0);
|
||||
*
|
||||
* Here we finish the example. The full source code can be found at
|
||||
* @ref test_slider_c.
