Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present invention, there is provided a method embodiment for correction of a collision profile, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.
Fig. 1 is a flowchart of a method for correcting a collision shape according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, determining that an abnormal collision form exists between a first three-dimensional virtual model and a second three-dimensional virtual model in a game scene in the collision detection process by adopting a narrow-phase collision detection algorithm;
step S104, correcting the abnormal collision form and recovering the abnormal collision form to the normal collision form.
Through the steps, the purpose of correcting the abnormal collision form can be achieved, and the technical problem that the collision calculation result is affected due to the abnormal collision form is solved.
Because the narrow-phase collision detection algorithm discretely detects that an abnormal collision form possibly exists between two three-dimensional virtual models in the game scene, if the abnormal collision form exists between the two three-dimensional virtual models in the game scene in the collision detection process by adopting the narrow-phase collision detection algorithm, the abnormal collision form is corrected, and the abnormal collision form is restored to the normal collision form. The abnormal collision form is corrected, so that the dissonance of a collision process picture can be prevented, and the problem that the collision calculation result is influenced due to the abnormal collision form is solved.
Alternatively, determining that an abnormal collision morphology exists between the first three-dimensional virtual model and the second three-dimensional virtual model may be: detecting the motion state change trend between the first three-dimensional virtual model and the second three-dimensional virtual model in each frame of image in sequence by using a discrete collision detection mode; and determining that the abnormal collision form exists in the current frame image according to the motion state change trend.
The motion state change trend between two three-dimensional virtual models in each frame of image is detected once, and abnormal collision of the two three-dimensional virtual models can be judged according to two continuous frames of images, so that the motion state change trend between the first three-dimensional virtual model and the second three-dimensional virtual model in each frame of image is sequentially detected in a discrete collision detection mode, and the abnormal collision form in the current frame of image is determined. Taking the application scene of the bullet passing through the wall as an example, detecting the positions of the bullets frame by frame until the abnormal collision form of the bullets and the wall is determined.
Optionally, the correcting the abnormal collision shape and recovering the abnormal collision shape to the normal collision shape may be: determining a compensation amount according to the abnormal collision form; and adopting the compensation quantity to restore the abnormal collision form to the normal collision form.
After the abnormal collision form of the bullet and the wall is determined, the bullet is retreated through compensation quantity correction, so that the collision form of the bullet and the wall is restored from the abnormal collision form to the normal collision form.
Optionally, determining the compensation amount according to the abnormal collision morphology includes: calculating a first physical settlement result between the first three-dimensional virtual model and the second three-dimensional virtual model under the abnormal collision form by adopting a discrete collision detection mode; and (3) referring to a second physical settlement result corresponding to the critical state between the abnormal collision form and the normal collision form, and adjusting the first physical settlement result to obtain the value range of the compensation quantity.
Optionally, restoring the abnormal crash configuration to the normal crash configuration using the compensation amount includes: selecting compensation quantity from the value range; and correcting the first physical settlement result by adopting the compensation quantity so as to recover the abnormal collision form to the normal collision form.
The correction of the abnormal collision state may be to determine a compensation amount and correct the abnormal collision state by using the compensation amount. For example, assuming that the game scene is that the bullet passes through the wall, the previous frame of image bullet has not hit the wall, the next frame of image bullet has penetrated the wall, the dissonance of the collision is corrected, the normal collision between the bullet and the wall has a normal collision range, the first physical settlement result is adjusted by referring to the second physical settlement result corresponding to the critical state between the abnormal collision form and the normal collision form, the value range of the compensation amount is obtained, and the recovery of the abnormal collision form by adopting the compensation amount in the value range can enable the bullet to return to the normal collision form with the wall.
