Sometimes "contact with object's hitbox" is not detected while moving

ACTION GAME MAKER BugReports

When a player or other object moves within the scene and comes into contact with an attack hitbox such as an enemy bullet, the condition “Object contacts attack hitbox” in the link condition may not be detected.

For example, this occurs when a player moving left is caught by an enemy bullet fired from the right. (The condition is correctly detected when the player is stationary or moving right.)

Since this issue only occurs with specific objects and not others, I investigated the conditions in the sample project’s tutorial project and found that it happens when a HitCollision is registered in the “Disabled HitCollision List” of the BaseSettings for Object_Sampleplayer.

I have attached a video and a diff file of the tutorial project for verification. The video shows that when the player is stationary, moving right, or moving left, the “Object contacts attack hitbox” link state is not entered only when moving left (indicated by the absence of the red “Damage​:double_exclamation_mark:” text).

In the combat scene where players shoot bullets to hit monsters, there are cases where bullets hit and disappear (indicating successful attack detection), but the monsters do not lose health (no hit detection is perceived).
There is a certain probability—approximately once every five or ten shots—where a monster may fail to register being hit.
I originally wanted to reproduce this issue to see if it could be resolved in this post as well.

I have confirmed the reproduction, so I will report it to the development team as a bug. Thank you.

@serbow
Upon checking in my environment, HP decreased normally.
Therefore, your issue may be caused by a different bug.

Then I’ll open a separate post to reproduce the issue that occurred. Thank you for your reply, Mr. BAZ.
