[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0037] An embodiment of the present invention provides an information - processing method for picking up a virtual item in the UE4 engine, as Figure 1As shown, the information processing method for picking up virtual items in the UE4 engine includes the following steps:
[0038] S102, creating a left hand skeleton model and a right hand skeleton model on the virtual item of the UE4 engine.
[0039] In this embodiment, a virtual item is created on the UE4 engine, and a left hand skeleton model and a right hand skeleton model are created at the same time. Specifically, the virtual item picked up is an Actor. Two static models are created on the Actor, namely a left hand (leftHandMesh) skeleton model and a right hand (rightHandMesh) skeleton model. The left hand (leftHandMesh) skeleton model and the right hand (rightHandMesh) skeleton model can be skeleton models of the hand posture that the virtual item perfectly fits created by the artist. For example, Figure 2 As shown in the figure, the virtual item picked up is a claw hammer, and the artist needs to create a skeletal model of the hand holding the claw hammer, and then the R&D personnel will convert it into a static model in UE4. At the same time, by adjusting the position of leftHandMesh and rightHandMesh, it can fit the Actor perfectly.
[0040] S104, adding a first slot to the first wrist node of the left hand skeleton model, and adding a second slot to the second wrist node of the right hand skeleton model.
[0041] In this embodiment, a first slot is added to the first wrist node of the left hand skeleton model, and a second slot is added to the second wrist node of the right hand skeleton model. Specifically, a socket is added to the wrist nodes (wrist_l) and (wrist_r) of the skeleton models of the left and right hands of the player, respectively. Socket means: a point is placed on a certain part of an object, and this point will move with the object. This point is the socket, and then another object is attached to this socket point of the object, and the other object will also move with the object. The first slot and the second slot are named Socket_l and Socket_r, respectively.
[0042] S106, when the player picks up the virtual item with his left hand, the first slot is passed to the AttachToComponent function, the pick-up event of the UE4 engine is called to output that the player picks up the virtual item with his left hand, and the SetVisibility function of the UE4 engine is called to hide the left hand of the player and display the left hand skeleton model.
[0043] In this embodiment, when the player picks up a virtual item, the AttachToComponent function of the UE4 engine is called, and the Socket on the hand of the corresponding virtual item to be picked up is passed into this function. Specifically, when it is necessary to pick up a virtual item, the pickup event (OnPickupEvent) is called, and parameters are passed out to determine that the bone model (HandMesh) of the hand for picking up is the left hand bone model and the enumeration of the left hand. According to these two parameters, the SetVisibility function of the UE4 engine is called to hide the player's real left hand and display the fake left hand that perfectly fits the corresponding virtual item Actor, that is, to display the left hand bone model. Therefore, the visual fit between the player's left hand and the virtual object can be achieved.
[0044] In one embodiment, after S106, it further includes: creating a first boolean variable, where the first boolean variable is used to adjust the positional relationship between the left hand and the virtual item; if the output value of the first boolean variable is true, the left hand of the player and the left hand bone model are displayed.
[0045] Preferably, after displaying the left hand of the player and the left hand bone model, it further includes: when the player is running, adjusting the position and rotation of the first socket so that the left hand of the player and the left hand bone model coincide.
[0046] Specifically, a bool variable IsAdjustSocket is created to adjust the positional relationship between the virtual item and the left hand. If this value is true, when the player picks up the virtual item, both the real left hand and the fake left hand on the item, that is, the left hand bone model, are displayed. Then, during running, by adjusting the position and rotation of the first socket, the real left hand and the left hand bone model on the virtual item are roughly coincident. At this time, the effect is that when picking up the virtual item, the fake left hand and the real left hand on the virtual item have the same position and rotation, that is, the virtual item and the real left hand are perfectly fitted. At this time, if the player's real left hand is hidden, there will be no feeling of being exposed. So at this time, IsAdjustSocket is set to false again and run again, and the effect of the virtual item and the left hand being perfectly fitted when picking up can be obtained.
[0047] In one embodiment, after S106, it further includes: when the player drops the virtual item, the drop event of the UE4 engine is called to output that the player drops the virtual item with the left hand, and the SetVisibility function of the UE4 engine is called to display the left hand of the player and hide the left hand bone model.
[0048] Specifically, when the player drops the virtual object, the drop event (OnDropEvent) is also called, and the above-mentioned left hand bone model and the enumeration of the left hand need to be passed in as two parameters. Similarly, by calling the SetVisibility function of the UE4 engine, the player's real left hand is displayed, and the corresponding fake left hand that perfectly fits the Actor is hidden, that is, the left hand bone model is hidden. Therefore, the visual effect when the player drops the virtual item is improved by displaying the real left hand and hiding the left hand bone model.
[0049] S108. When the player picks up the virtual item with the right hand, the second socket is passed into the AttachToComponent function, and the pick-up event of the UE4 engine is called to output that the player picks up the virtual item with the right hand, and the SetVisibility function of the UE4 engine is called to hide the right hand of the player and display the right hand bone model.
[0050] In this embodiment, when the player picks up the virtual item, the AttachToComponent function of the UE4 engine is called, and the Socket on the hand of the corresponding virtual item to be picked up is passed into this function. Specifically, when the virtual item needs to be picked up, the pick-up event (OnPickupEvent) is called, and parameters are passed out to determine that the bone model (HandMesh) of the hand for picking up is the right hand bone model and the enumeration of the right hand. According to these two parameters, the SetVisibility function of the UE4 engine is called to hide the player's real right hand and display the corresponding fake right hand that perfectly fits the virtual item Actor, that is, to display the right hand bone model. Therefore, the fitting of the player's left hand and the virtual object can be achieved visually.
[0051] In one embodiment, after S108, it further includes: creating a second boolean variable, and the second boolean variable is used to adjust the positional relationship between the right hand and the virtual item; if the output value of the first boolean variable is true, the right hand and the right hand bone model of the player are displayed.
[0052] Preferably, after displaying the right hand and the right hand bone model of the player, it further includes: when the player is running, adjusting the position and rotation of the second socket so that the right hand and the right hand bone model of the player coincide.
[0053] Specifically, a bool variable IsAdjustSocket is created to adjust the positional relationship between the virtual item and the right hand. If this value is true, when the player picks up the virtual item, both the real right hand and the fake right hand on the virtual item, that is, the right hand bone model, are displayed. Then during operation, by adjusting the position and rotation of the second slot, the real right hand and the right hand bone model on the virtual item are roughly coincident. At this time, the effect is that when picking up the virtual item, the positions and rotations of the fake right hand on the virtual item and the real right hand are the same, that is, the virtual item and the real right hand are perfectly fitted. At this time, if the player's real right hand is hidden, there will be no feeling of being exposed. So at this time, set IsAdjustSocket to false again and run again to obtain the effect that the virtual item and the right hand are perfectly fitted when picking up.
[0054] In one embodiment, after S108, it further includes: when the player drops the virtual item, call the drop event of the UE4 engine to output that the player drops the virtual item with the right hand, and call the SetVisibility function of the UE4 engine to display the player's right hand and hide the right hand bone model.
[0055] Specifically, when the player drops the virtual object, the drop event (OndropEvent) is also called, and the above two parameters, namely the right hand bone model and the enumeration of the right hand, also need to be passed in. Similarly, by calling the SetVisibility function of the UE4 engine, the player's real right hand is displayed, and the corresponding fake right hand that is perfectly fitted to the Actor, that is, the right hand bone model, is hidden. Therefore, the visual effect when the player drops the virtual item is improved by the way of displaying the real right hand and hiding the right hand bone model.
[0056] By implementing the above method, a left - hand bone model and a right - hand bone model are created on the virtual item in the UE4 engine; a first slot is added to the first wrist node of the left - hand bone model, and a second slot is added to the second wrist node of the right - hand bone model; when the player picks up the virtual item with the left hand, the first slot is passed into the AttachToComponent function, the pick - up event of the UE4 engine is called to output that the player picks up the virtual item with the left hand, and the SetVisibility function of the UE4 engine is called to hide the left hand of the player and display the left - hand bone model; when the player picks up the virtual item with the right hand, the second slot is passed into the AttachToComponent function, the pick - up event of the UE4 engine is called to output that the player picks up the virtual item with the right hand, and the SetVisibility function of the UE4 engine is called to hide the right hand of the player and display the right - hand bone model. Therefore, whether the player picks up the virtual item with the left hand or the right hand, the perfect fit between the left - hand bone model or the right - hand bone model and the virtual item can be shown, thus achieving the visual fit between the player's hand and the virtual object.
[0057] In one embodiment, the present invention further provides an information processing device for picking up virtual items in the UE4 engine. As Figure 3 shown, the device includes:
