Wow thank you for the extra quick answers  !

Christopho, that seems to perfectly fit, thank you ! Diarandor I'll watch your videos on the train .

For example, I want that a character named Sheik does this pattern at the map's loading :
- few steps upward
- face left
- wait few time
- few steps downward

Here is the quicker way to code that I found :

Code Select Expand

function sheik_intro_movement()
  local step = 0
  local movement = sol.movement.create("path")
  movement:set_speed(64)
  movement:start(sheik)
  function movement:on_finished()
    if step == 0 then
      movement:set_path{2,2,2,2,2,2}
      movement:start(sheik)
      step = step + 1
    elseif step == 1 then
      sheik:get_sprite():set_direction(2)
      sol.timer.start(200, function()
        step = step + 1
        movement:on_finished()
      end)
    elseif step == 2 then
      movement = sol.movement.create("path")
      movement:set_speed(64)
      movement:set_path{6,6,6,6,6,6}
      movement:start(sheik)
      step = step + 1
    end
  end
end

Please note that in step 2 I'm realocating the movement variable

Code Select Expand

movement = sol.movement.create("path") because if I just do

Code Select Expand

movement:set_path{2,2,2,2,2,2}, the character is teleported at the destination for some reason.

Hello 

I'm starting with Solarus engine and I was wondering : is it possible to create complex movements including changement of directions and pause?
Something like :
movement.add(straight_movement(east))
movement.add(wait(5))
movement.add(facing(east))
movement.add(jumping(right))

For the moment, I don't understand how to include a pause in a movement, and the only way I find to change a direction after a movement is to create a lot of movement:on_finished() which is pretty redundant.
Sorry if the solution already exist, I didn't manage to find it in the documentation :S.
