Hello guys,
I am currently making a game like megaman. I implemented all the game mechanics (gravity, jumping, shooting, enemies, animations etc) however there is a problem. When I assign my main character's fire (projectile) physics into kinematic and when I use GetSpriteFirstContact() I can't detect any collision. However if I assign it's physics to dynamic it works perfectly. But If I assign projectile sprite to dynamic, projectiles don't pass through walls. What can I do for this situation? How can I check the collision of sprites that have kinematic physics?
Thank you.

You could use Sprite groups, but an easier method would be to make you projectiles a sensor... This allows collision detection, but also allows them to pass through other physic sprites...

SetSpritePhysicsIsSensor()

Thank you so much, it helped a lot. But still I need to use it with dynamic physics. Now projectiles can pass through walls but they don't go straight because I have gravity in the game.

Bump for changing to question,
Now projectiles pass through objects with SetSpritePhysicsIsSensor() even though their physics are dynamic, how can I close gravity for spesific sprite with physics?
Thanks

Solved the problem by using SetSpritePhysicsForce().
