XNA - Colize

[CallManyCZ]

Ahoj,
Vyvíjím hru v XNA .. Bude to něco jako terraria, vím moc mainstream, ale to teď nechci slyšet. Chtěl bych po vás radu, a to ohledně kolizí.
Kolize fungujou, ale když chci slézt z 1 blocku o block níže , tak panáček jakoby by létal ve vzduchu.
Zde máte obrázek jak to zatím vypadá : https://ctrlv.cz/dSt1

Zde jsou moje třídy:
