Algorithmique du cycle 4 - 4e

Niveau 1 : tracés, déplacements & calculs

Exercice 1 : Déplacement véhicule - Découvrir l'algorithmie par bloc (1/6)

Déplacer le bloc {"options": {"blockly": {"readOnly": true}, "blocks": {"road_forward": {"previous_statement": true, "next_statement": true, "colour": 160, "tooltip": "Avancer d'une case tout droit", "inputs": [{"type": "dummy_input", "fields": [{"text": "Avancer de 1 case", "type": "text"}], "align": "left"}]}}}, "ast": [[{"type": "road_forward"}]]} pour faire avancer le véhicule vers la tour.

Exemple:

{"environment": "road", "timeout": 100, "move_duration": 400, "rotation_duration": 200, "map": [[0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 3, 1, 2, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]], "start_direction": 3, "boat_start_direction": null}

Exercice 2 : Déplacement véhicule - Utiliser plusieurs blocs (2/6)

Utiliser maintenant le bloc {"options": {"blockly": {"readOnly": true}, "blocks": {"road_forward": {"inputs": [{"fields": [{"text": "Avancer de 1 case", "type": "text"}], "align": "left", "type": "dummy_input"}], "colour": 160, "next_statement": true, "tooltip": "Avancer d'une case tout droit", "previous_statement": true}}}, "ast": [[{"type": "road_forward"}]]} autant de fois que nécessaire pour atteindre la tour.

{"environment": "road", "map": [[0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 2, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0, 0, 0, 3, 0, 0, 0, 0, 0]], "move_duration": 400, "rotation_duration": 200, "start_direction": 2, "timeout": 100, "boat_start_direction": null}

{"options": {"toolbox": [{"type": "road_forward"}], "blocks": {"base_start": {"inputs": [{"fields": [{"text": "Au d\u00e9marrage", "type": "text"}], "align": "left", "type": "dummy_input"}], "on_event": "start", "creatable": false, "tooltip": "D\u00e9marrage de l'algorithme", "colour": 65, "next_statement": true}, "road_forward": {"inputs": [{"fields": [{"text": "Avancer de 1 case", "type": "text"}], "align": "left", "type": "dummy_input"}], "colour": 160, "next_statement": true, "tooltip": "Avancer d'une case tout droit", "previous_statement": true}}}, "ast": [[{"editable": false, "type": "base_start", "deletable": false}]]}
