i get camera drift, when setting up fps camera movement #14484
Description
xrel and yrel never returns 0, its 0 when i start the program. when i move the mouse my fps camera moves "normally", but when i stop moving the mouse the camera starts drifting. xrel and yrel returs either 1 or -1 sometimes higher numbers, but rarely.
this happens even when i lift the mouse, or disconnect it(im on a desktop, not a laptop).
this is parts of my code related to mouse movement. not sure if xrel and yrel are floats or not, but making my getters floats makes my camera spinn uncontrollably.
if its relevant i'm running manjaro linux, and i'm using whatever version of sdl3 that is in the manjaro repository as of today.
my getters
int EngineInput::GetMouseXRel(){
//cout << m_relativeMousePos.x << endl;
return m_relativeMousePos.x;
}
int EngineInput::GetMouseYRel(){
return m_relativeMousePos.y;
}
poll event
while(SDL_PollEvent(&m_event)){
if(m_event.type == SDL_EVENT_MOUSE_MOTION){
m_relativeMousePos=glm::vec2(m_event.motion.xrel,m_event.motion.yrel);
}
}
//game logic
xrot = e->Input.GetMouseXRel() * 60; //xrel multiplied by sensitivity, i have messed around with different ways of doing this with no luck.
yrot = e->Input.GetMouseYRel() * 60;
e->Scene.Rotate("Player",glm::vec3(0,-xrot * e->Time.DeltaTime(),0));
e->Scene.Rotate("Player/Camera",glm::vec3(-yrot * e->Time.DeltaTime(),0,0));
