The topics being considered in the study is to compare the text input methods in the mobile network communicator. Analyzed the speed of text entry as well as the number of mistakes made by users via the tested methods. Compared the methods of entering text using the QWERTY keyboard, Swype Technology, Handwriting and voice commands. The study was conducted among the two groups of respondents, by age of the participants. There have been characteristics of the selected text input methods in the mobile network communicator. On the needs of the article was developed mobile communicator.

The study describes and characterises BOID (bird-oid object) type behaviours, consisting of joint movement of a cluster of objects with the same properties. Authors presented Reynolds’ model, which takes into account 3 rules: separation, alignment and consistency, as well as the control procedures of a cluster of objects suggested by Parker, considering such variables as wind, aim, speed, order and the occurring forces. The test method was to conduct simulation experiments with different configurations of coefficients of the forces controlling the model. For each simulation the time of moving from the start point to the end point was measured. A hundred simulations were carried out for each individual group of coefficients, and then, using the described statistics methods, generalised time values were determined. This allowed a comparison of the results and made a conclusions. The numerical simulations carried out were implemented in Unity environment. Calculating the time required for travelling the same route was done by changing the value of the separation force, cohesion, alignment and avoidance. From the values obtained, it can be seen that the biggest influence on the increase of the time of moving BOID objects, is increasing value of the coefficient of separation and levelling forces. Unity environment is well suited to conduct such simulations, since it allows to obtain both numerical values and process visualization as a 3D image. In addition, Unity allows to create individual scripts to manage simulation in individual IDEs, and consists reliable documentation, which simplifies their writing.

The comparative analysis was made on the basis of technical documentation selected tools and on the process of creating a sample web application. Strengths of each tool were selected and have been used in the process of developing a web application that combines frameworks by assigning each of them a specific application functionality. Combining of frameworks aimed increasing the efficiency of the developing process of web application.

Game optimization is one of the most important aspects of their creation. The article describes methods to optimize Unity Engine using third person perspective game as an example. Various methods that rely on offloading graphics card, by increasing the use of CPU and memory were used in order to check how the game performance changes.

This document reviews research in efficiency analysys of particles created by Unity 3D built-in particle system compared to those created via sctript written in C# language. Author focused his research on examining the impact of the various tasks on the speed of rendering frames, a difference which occur during the generation of particle by particle system and those generated by a script, and how influential is the complexity of the mesh particles generated on the application performance. For this purpose, using Unity3D, Microsoft Visual Studio and Blender, an applications for computers that are ruunniong on Windows system was created, application allows to adjust the simulation parameters (the number of generated particles, particle shape - sphere, cube).
