Hi,

beside using c_move, c_rotate and other c functions, is there other ways to check whether the entity has collide with another entity or check whether an entity has overlap another one.

Thanks and appreciate all the helps

only if you program one by yourself

you can use c_content to check whether a world position is in a solid (level block or walls) Thus, you can check if the vertices of your entity are within a solid. I've used this method before.

1. Move the entity
2. Check if the vertices are within a solid (using c_content)
3. If they are move the entity back, otherwise leave it where it is
4. use a wait command to allow the frame to be drawn.
5. If you need to check if the entity has hit another model you can create a wmb that matches the shape of your model and then move it with your entity.

but he doesnt want to use and c_ functions and c_content is the c_ func

if you don't want to use c_ functions then the answer is ... no

though you can you use c_scan c_trace and c_content for scanning environments but without using movement, if that's what you're trying to not use

otherwise... no...

Thanks for all the replies.

The reason i did not want to use c_ functions is because i am creating a rts game and when the player want to construct a building, it needs to check whether the building collide with other entities in the world before it can place the building on that location where the mouse cursor is.

i might be wrong of thinking not to use any c_ functions but since the "unconstructed" building is following the mouse cursor, there might not be any chances to use any c_ functions

Create an invisible building entity that follows the mouse by
using c_move from "where the house is now" to "where the mouse is now",
checking for collisions along the way.

Plausable?

Thanks for your idea, EvilSOB but instead of using c_move, i have use c_rotate with the building when the player click at that particular position to see whether collision has occured while rotate and so far is working fine.

Thanks to all other who have giving me ideas.
