SubmitQuad render position error
by DieRich · in Torque 2D Beginner · 04/27/2014 (11:29 pm) · 4 replies
hi all, I create a class inherited from SceneObject, and in function sceneRender() I called SubmitQuad() as:
vertexPos0 = Vector2(0, mSize.y) + getPosition();
vertexPos1 = Vector2(mSize.x, mSize.y) + getPosition();
vertexPos2 = Vector2(mSize.x, 0) + getPosition();
vertexPos3 = Vector2(0, 0) + getPosition();
pBatchRenderer->SubmitQuad( vertexPos0, vertexPos1, vertexPos2, vertexPos3,
Vector2( 0, 1 ),
Vector2( 1, 1 ),
Vector2( 1, 0 ),
Vector2( 0, 0 ),
mTextureHandle );
but image render postion is error, and I tried getRenderPosition(), it returns (0, 0).
why is that? any clue is thankful.
thanks.

Are you setting the SceneObject position in script as well? What happens when you setPosition to multiple spots? Does the render position change?

Box2D/Torque 2D uses meters as its unit of length so a sprite that is 6x6 is 6 meters wide in X and 6 meters high in Y. The camera view is typically set to something like 100x75 (100 meters wide by 75 meters high) which is a 4:3 aspect ratio to fit with a computer monitor resolution like 1024x768.
Local coordinates have 0,0 as the center of an object.

The world coordinate system comes from the standards used by Box2D - which is your normal cartesian coordinates:Box2D/Torque 2D uses meters as its unit of length so a sprite that is 6x6 is 6 meters wide in X and 6 meters high in Y. The camera view is typically set to something like 100x75 (100 meters wide by 75 meters high) which is a 4:3 aspect ratio to fit with a computer monitor resolution like 1024x768.
