From e42eeec8f626acbaa54ae31c10ca06c868c7931c Mon Sep 17 00:00:00 2001 From: MirceaKitsune Date: Sat, 27 Oct 2012 01:49:01 +0300 Subject: [PATCH] Framework for the attachment system, new object property which allows changing the color and alpha of mesh materials New object property which allows changing the color and alpha of mesh materials. Due to the current lighting systems it doesn't work yet, but the full implementation is there Framework for the attachment system, with no actual functionality yet Send bone and player object to the setAttachment function in content_sao.cpp, but we need a way to translate it there and send it to the client I will also want position and rotation offsets to be possible to apply to attachments Network object ID from server to client. This will be used to identify the parent client-side and know what to attach to --- doc/lua_api.txt | 3 +-- src/content_cao.cpp | 40 ++++++++++++++++++++++++++++++++++ src/content_sao.cpp | 26 ++++++++++++++++++++++ src/content_sao.h | 2 ++ src/genericobject.cpp | 11 ++++++++++ src/genericobject.h | 7 ++++-- src/object_properties.cpp | 15 +++++++++++++ src/object_properties.h | 1 + src/scriptapi.cpp | 45 +++++++++++++++++++++++++++++++++++++++ src/serverobject.h | 2 ++ src/util/serialize.h | 33 ++++++++++++++++++++++++++++ 11 files changed, 181 insertions(+), 4 deletions(-) diff --git a/doc/lua_api.txt b/doc/lua_api.txt index c99e8035..cb84b545 100644 --- a/doc/lua_api.txt +++ b/doc/lua_api.txt @@ -1232,9 +1232,8 @@ Object Properties visual = "cube"/"sprite"/"upright_sprite"/"mesh", visual_size = {x=1, y=1}, mesh = "model", - animation_bone_position = {"", {x=0, y=0, z=0}}, -- bone name followed by position vector - animation_bone_rotation = {"", {x=0, y=0, z=0}}, -- bone name followed by rotation vector textures = {}, -- number of required textures depends on visual + colors = {}, -- number of required colors depends on visual spritediv = {x=1, y=1}, initial_sprite_basepos = {x=0, y=0}, is_visible = true, diff --git a/src/content_cao.cpp b/src/content_cao.cpp index b12bfe1c..3e18337d 100644 --- a/src/content_cao.cpp +++ b/src/content_cao.cpp @@ -555,6 +555,7 @@ private: std::string m_name; bool m_is_player; bool m_is_local_player; // determined locally + int m_id; // Property-ish things ObjectProperties m_prop; // @@ -596,6 +597,7 @@ public: // m_is_player(false), m_is_local_player(false), + m_id(0), // m_smgr(NULL), m_irr(NULL), @@ -640,6 +642,7 @@ public: } m_name = deSerializeString(is); m_is_player = readU8(is); + m_id = readS16(is); m_position = readV3F1000(is); m_yaw = readF1000(is); m_hp = readS16(is); @@ -930,6 +933,7 @@ public: addToScene(m_smgr, m_gamedef->tsrc(), m_irr); updateAnimations(); updateBonePosRot(); + updateAttachment(); } if(m_prop.physical){ @@ -1062,6 +1066,10 @@ public: texturestring += mod; m_spritenode->setMaterialTexture(0, tsrc->getTextureRaw(texturestring)); + + // Does not work yet with the current lighting settings + m_meshnode->getMaterial(0).AmbientColor = m_prop.colors[0]; + m_meshnode->getMaterial(0).DiffuseColor = m_prop.colors[0]; } } if(m_animated_meshnode) @@ -1087,6 +1095,12 @@ public: material.setFlag(video::EMF_LIGHTING, false); material.setFlag(video::EMF_BILINEAR_FILTER, false); } + for (u32 i = 0; i < m_prop.colors.size(); ++i) + { + // Does not work yet with the current lighting settings + m_animated_meshnode->getMaterial(i).AmbientColor = m_prop.colors[i]; + m_animated_meshnode->getMaterial(i).DiffuseColor = m_prop.colors[i]; + } } } if(m_meshnode) @@ -1113,6 +1127,10 @@ public: material.setTexture(0, atlas); material.getTextureMatrix(0).setTextureTranslate(pos.X, pos.Y); material.getTextureMatrix(0).setTextureScale(size.X, size.Y); + + // Does not work yet with the current lighting settings + m_meshnode->getMaterial(i).AmbientColor = m_prop.colors[i]; + m_meshnode->getMaterial(i).DiffuseColor = m_prop.colors[i]; } } else if(m_prop.visual == "upright_sprite") @@ -1126,6 +1144,10 @@ public: scene::IMeshBuffer *buf = mesh->getMeshBuffer(0); buf->getMaterial().setTexture(0, tsrc->getTextureRaw(tname)); + + // Does not work yet with the current lighting settings + m_meshnode->getMaterial(0).AmbientColor = m_prop.colors[0]; + m_meshnode->getMaterial(0).DiffuseColor = m_prop.colors[0]; } { std::string tname = "unknown_object.png"; @@ -1137,6 +1159,10 @@ public: scene::IMeshBuffer *buf = mesh->getMeshBuffer(1); buf->getMaterial().setTexture(0, tsrc->getTextureRaw(tname)); + + // Does not work yet with the current lighting settings + m_meshnode->getMaterial(1).AmbientColor = m_prop.colors[1]; + m_meshnode->getMaterial(1).DiffuseColor = m_prop.colors[1]; } } } @@ -1168,6 +1194,11 @@ public: } } + void updateAttachment() + { + // Code for attachments goes here + } + void processMessage(const std::string &data) { //infostream<<"GenericCAO: Got message"<getName()); // name writeU8(os, 1); // is_player + writeS16(os, getId()); //id writeV3F1000(os, m_player->getPosition() + v3f(0,BS*1,0)); writeF1000(os, m_player->getYaw()); writeS16(os, getHP()); @@ -1109,6 +1126,15 @@ void PlayerSAO::setBonePosRot(std::string bone, v3f position, v3f rotation) m_messages_out.push_back(aom); } +// Part of the attachment structure, not used yet!
