Question

Im trying to implement jumping mechanics so i have 2 states, falling and jumping. I code it this way that if its not jumping its falling and the other way around, bool switches when player is at the pick of jump and thats when jumpSpedDecrease > 0.299f, in code there u can see that in that if statement theres cout saying "This code should work". When i run program i can see this in code but the values i change there stay same way, but it obviously should change.
if (isJumping)
{
fallingSpeed = 0;
falSpedIncrease = 0;
birdSprite.setPosition(pos.x, pos.y - (jumpStartSped - jumpSpedDecrease) * time.asMilliseconds() * jumpingSpeed);
jumpSpedDecrease += jumpSpedDcrsValue;
std::cout << " jumpStartSped: " << jumpStartSped << " jumpSpedDecrease: " << jumpSpedDecrease << " jumpSpedDcrsValue: " << jumpSpedDcrsValue << " fallingSpeed: " << fallingSpeed << std::endl;
if (jumpSpedDecrease > 0.299f)
{
float fallingSpeed = 1;
float startSped = 0.004f;
float falSpedIcrsValue = 0.001f;
float falSpedIncrease = 0;
float jumpingSpeed = 1;
float jumpStartSped = 0.3f;
float jumpSpedDcrsValue = 0.001f;
float jumpSpedDecrease = 0;
std::cout << "This code should work" << std::endl;
}
if (jumpSpedDecrease > 0.3f) isJumping = false;`

Reconsider these lines:
if (jumpSpedDecrease > 0.299f)
{
float fallingSpeed = 1;
float startSped = 0.004f;
float falSpedIcrsValue = 0.001f;
float falSpedIncrease = 0;
float jumpingSpeed = 1;
float jumpStartSped = 0.3f;
float jumpSpedDcrsValue = 0.001f;
float jumpSpedDecrease = 0;
std::cout << "This code should work" << std::endl;
}
if (jumpSpedDecrease > 0.3f) isJumping = false;
Here you just create some local variables (e.g. float jumpSpedDecrease = 0), thereby not modifying the class fields. For example, the fallingSpeed (class field) set to 0 here:
if (isJumping)
{
fallingSpeed = 0;
falSpedIncrease = 0;
is not set back to 1, when the jump ends. And you use this field in the falling() method. I suggest removing float type specifiers first (inside of if (jumpSpedDecrease > 0.299f) {} statement).
