Dans les logiciels 3D, le bouton gauche est enfonc\u00e9 pour observer. Pour d\u00e9clencher une action, il faut lib\u00e9rer le bouton, positionner la souris au niveau de la zone sensible et cliquer. Ces actions, devenue naturelles, n\u2019existent pas en standard dans Unity de fait de l\u2019h\u00e9ritage \u00ab jeux vid\u00e9o \u00bb. Il faudra d\u00e8s lors ajouter un script qui modifiera l\u2019ergonomie de base du logiciel.<\/p>\n

<\/p>\n

\"clip_image004\"<\/a><\/p>\n

Le script va s\u2019appliquer sur l\u2019objet \u00ab first person controller \u00bb. Cet objet est compos\u00e9 de la capsule d\u00e9crivant l\u2019encombrement du personnagle et de la cam\u00e9ra (Main Camera) restituant le point de vue. L\u2019ensemble est combin\u00e9 dans un objet parent le \u00ab First Person Controller \u00bb.<\/p>\n

\"clip_image005\"<\/a><\/p>\n

Le script va s\u2019appliquer \u00e0 deux niveaux diff\u00e9rents : le niveau First Person Controller pour la gestion des axes X et dans le Main Camera pour la gestion des axes Y<\/p>\n

Cr\u00e9er un script C#<\/span><\/strong> et dans Monodevelop copier ci-dessous.<\/p>\n

Le script est le suivant :<\/p>\n

Dans le First Person Controller<\/span>, il faut ajouter le script, les r\u00e9glages suivants peuvent \u00eatre appliqu\u00e9s. Il faut surtout penser \u00e0 choisir l\u2019axe X<\/span><\/p>\n
\"clip_image006\"<\/a><\/p>\n
Dans le Main Camera<\/span>, le m\u00eame script est appliqu\u00e9 mais cette fois selon l\u2019axe Y<\/span>.<\/p>\n
\"clip_image007\"<\/a><\/p>\n
Il faut bien prendre garde de d\u00e9sactiver pour effacer le script MouseLook, afin de ne pas g\u00e9n\u00e9rer de conflits.<\/p>\n
\"clip_image008\"<\/a><\/p>\n
Il ne reste plus qu\u2019\u00e0 tester.<\/p>\n
